North America

1. Profundulus oaxacae habitat

Víctor Manuel Ortiz Cruz (San Lorenzo Cacaotepec, México)
Aquarium Volume: 140 l
Aquarium Age: 2 months
Animals: Profundulus oaxacae, Poecilia sphenops
Plants: Eleocharis parvula, Bacopa monnieri, Chara sp., Ludwigia peploides, Sphagnum sp., Pteridophytes sp., Fissidens crispus, Azolla caroliniana, Heteranthera reniformis, unknown species
Biotope description: This aquarium was set up based on the recently discovered population of the killifish Profundulus oaxacae, a species about which very little is known and which is on the border of extinction due to the destruction and contamination of the watershed in which it was abundant until several decades ago (the river Atoyac in the state of Oaxaca, Mexico). The habitat in which the 2nd confirmed existing population of this species was found is a micro watershed. More specifically it is the source of a stream which finds its way through a ravine surrounded by oak trees that constantly shed their leaves in the stream, and forming different small pools. The first known population is located several kilometers away from the newly discovered and their habitat (which was recreated for the contest), so they have no communication and are different populations. The stream finds its way through whitish rocks and the border is littered with small wooden trunks and roots, both covered with mosses with a large quantity of ferns, followed in abundance by Eleocharis parvula (there are other species of the same genus but this is the species that is in direct contact with the water). In the pools a native water lily can be found, as well as Ludwigia peploides, Bacopa monnieri, the macro algae Chara sp. At the bottom of the stream a small rosette type plant is found which has not been identified up to now. The bottom of the stream is mostly sandy covered with organic matter due to the decomposition of the oak leaves. It is worthwhile mentioning that the area of the recently discovered population of the Oaxacan killifish, is seriously threatened due to the advancing limits of the urban population. For this reason, the local municipal authority, together with a collective of environmentalists and the expertise of an aquatic biologist, that discovered the population, tries to protect this area and the Profundulus oaxacae. Through the participation in this contest we try to generate interest and awareness about these efforts in order to obtain support of those interested.

4. Lake Xochimilco in Mexico City

Svetlana Kirillova (St. Petersburg, Russia)
Aquarium Volume: 40 l
Aquarium Age: 1 month
Animals: Ambystoma mexicanum
Plants: Eichhornia crassipes
Biotope description: Lake Xochimilco in Mexico City is located in the south of the city and, in fact, is now a system of channels with a total length of about 170 km, which is a UNESCO World Heritage Site. These channels were formed as a result of the creation of numerous man-made islands - chinampas, where 1000 years ago local people cultivated flowers and made gardens. Mexico City is located at an altitude of over 2,200 meters above sea level and the water in the canals is cold enough (20 degrees Celsius in the summer, 12 in the winter), and the channel walls often consist of roots. Aquatic plants are mainly floating, bottom of the channels is covered with a thick layer of silt. The traditional system of gardening involves the use of water, sludge and algae from the lake for irrigation and fertilizing plants. Now because of the use of chemical fertilizers and the existence of a metropolis the lake's ecosystem is seriously damaged, and this especially reflected in the number of amazing endemic amphibian, the axolotl. Axolotl is a larval form of Mexican salamander, known for its ability to neoteny. In Aztec times axolotl was an important part of their diet, but now in the wild they are about to extinct, as in the lake African tilapia and Asian carp were introduced as fish culture. Along with pollution of the environment it caused significant damage to native fauna. So, in 2004, according to estimates of local biologists the population of axolotl was 1000 per 1 sq km, in 2008 it was already 100, and in 2009 Nick Baker within a few days found only one axolotl. We can only be glad that these amphibians breed well in captivity, and they do not seem threatened by the danger like dodo and the Steller's sea cow.

The river is formed from the confluences of several upper tributaries, such as Blue Creek and Chan Chich (Rio Bravo) which have their sources in Guatemala's Petén Basin region, and Booth's River which originates in the western Belizean district of Orange Walk. These tributaries join to form the Hondo River near the settlements of Blue Creek Village, on the Belizean side, and La Unión on the Mexican side. The river continues its northeastern course with few other settlements along its length until reaching its outlet in Chetumal Bay. The city of Chetumal, capital of the Mexican state of Quintana Roo and the region's main port, lies close to this outlet.

Plants: Micranthemum umbrosum, Ceratophyllum demersum, Lemna minor
Biotope description: The aquarium is inspired by swamps of Louisiana. The bottom of the swamp is covered with fallen leaves and pieces of wood. This is why the water has a peculiar brown color. The surface of water is covered by Lemna minor. These marshlands are a local ecosystem where hundreds of different species of animals live: from alligators lurking just around the corner to the smallest fish of North America: Heterandria formosa. These marshes are inhabited also by one of the smallest species of crayfish in the family Cambaridae: Cambarellus puer. Someone even saw there a Bigfoot.

1. Flooded forest in the bend of Rio Tapajos

Svetlana Kirillova (St. Petersburg, Russia)
Aquarium Volume: 180 l
Aquarium Age: 1 month
Animals: Pterophyllum scalare, Mesonauta festivus, Hemigrammus ocellifer
Plants: Limnobium laevigatum
Biotope description: Tapajos River flows through Brazil and is a right tributary of the Amazon River. Like other rivers of the Amazon region, it takes water from rains and during the flood period (November to March) the water level in the river rises up to 7-8 meters, flooding forests on its banks. Surprisingly, the trees, staying under water for several months, do not die, in fact their diversity on the flooded areas of the forest are higher. During the flood the living space of fishes significantly expands, some species move into the flooded forest area for breeding. The water tn the river is soft (total hardness is 0,31-0,82 dH), slightly acidic (pH 6,4-6,65), clear, has a slightly dark or greenish stain, so Tapajos commonly referred to as clearwater river. On the aea of the flooded forest there are no proper aquatic plants, except accidentally brought floating plants, the earth covered with a layer of leaves, and fish glide among trees in search of food and places for spawning. Branches with green leaves were placed in the aquarium the day before taking photo.

5. Rio Shishita, Rain Forest

Claire Moreira (Lisbon, Portugal)
Aquarium Volume: 180 l
Aquarium Age: 13 months
Animals: Apistogramma bitaeniata sp. Shishita, Nannostomus marginatus
Plants: Limnobium laevigatum
Biotope description: This biotope aquarium was created to be the home of a couple of wild Apistogramma bitaeniata sp. Shishita. Starting from here, a careful investigation was made about Rio Shishita biotope, finding very useful information on the trip journal “Collecting in Pebas, Río Orosa and Río Shishita 2008” by Tom Christoffersen and Mike Wise. In this particular biotope that I wanted to recreate I found that it should have a low water flow with very acidic and soft dark water, clear sand bottom, a lot of driftwood and fallen tree leafs, providing lot of burrows for the fish to hide and breed. I chose the Limnobium laevigatum because it is a native plant and is used to dim the lights and create an overall ambiance on the layout while providing shelter for the dither fish. Also the Nannostomus marginatus were chosen as they are one of the few smaller species that live along with Apistogramma bitaeniata sp. Shishita and because of their small size and mouth, it makes them an ideal dither fish as they aren't an active fry predator.

Animals: Symphysodon haraldi, Mesonauta insignis, Geophagus altifrons, Dicrossus filamentosus
Plants: Echinodorus bleheri
Biotope description: The aquarium was set up based on Rio Paracon biotope, a slow flowing semi blackwater habitat. Aquatic vegetation is sparse so I have only added two Echinodorus bleheri, as with most Amazonian rivers there is an abundance of submerged tree roots where discus will converge in large numbers. Also the floor is covered in leaf litter as you can see in my photos I have tried to replicate this where the flow of the water allows.

11. Rio Nanay, Fallen Tree

Nuno Matos (Lisbon, Portugal)
Aquarium Volume: 180 l
Aquarium Age: 8 months
Animals: Pterophyllum scalare sp. Rio Nanay, Apistogramma allpahuayo, Nannostomus marginatus
Biotope description: The main intention of this layout was to give scale to the Scalare, while trying to create space for them and areas that could delimit territories, had to be something imposing and at the same time free space around for the fish to swim freely. I tried to create here a plausible situation that could recreate their natural habitat (Rio Nanay, drainage Peru), the idea was to imagine these wood pieces as a bit of tree that cracked and as fallen to the bottom of a riverbed, this creates a darker and more sinister scenario that works for me because of the size and gracefulness of this strain of Pterphyllum scalare sp. Rio Nanay. In the search of information I’ve found that it is very unlikely to find rocks and submersed water plants, only a clear sand river bed with large driftwood, some fallen tree leafs and dark waters. So I chose to use Horn Wood along with ADA Colorado sand. As for plants I chose to use Limnobium laevigatum as it’s an endemic plant found in almost all of this river system. Also there is a school of Nannostomus marginatus, as well as a fabulous trio of Apistogramma allpahuayo, found in some tributaries of this river in the Iquitos / Loreto area.

13. Rio Guapore

Tolga Eldurmaz (Istanbul, Turkey)
Aquarium Volume: 45 l
Aquarium Age: 5 months
Animals: Apistogramma trifasciata, Poecilia wingei
Plants: Echinodorus sp.
Biotope description: In my country where I struggle to find Apistogramma species, A. trifasciata is my favourite. I wanted to set up a true biotope aquarium for this special species. I tried to replicate Rio Guapore, which is a small tributary in the Amazone river system and home to A. trifasciata. The water parameters are how they should be and the biological system in the tank is well established. My only maintenance routine is to top off the water which is lost daily through evaporation. The trifasciatas feed on the invertebrates and microorganisms growing in the aquarium.

Danett Williams (Missouri, USA)
Aquarium Volume: 110 l
Aquarium Age: 1 month
Animals: Nannostomus trifasciatus, Paracheirodon axelrodi
Plants: Echinodorous horizontalis, Eichhornia crassipes, Salvinia oblongifolia
Biotope description: In order to support the green industry of cardinal tetra farming in the Amazon which protects its powerful waters, cardinal tetras were employed in an aquarium representing a microcosm of the Rio Negro. The waters of the largest blackwater river worldwide, are acidic and warm. On the shore of the Rio Negro, Echinodorus horizontalis may be found. However, due to heavy rains it is found fully submerged amongst leaf litter. The tannin stained waters constrain light for aquatic life, leaving little more than floaters amidst the top of the water in this particular area. Cardinal tetras and Three Lined Pencilfish swim amongst the leaf littered bottom wherein the sand is stained with humic acid from decomposing plant matter. The waters are full of fallen branches from the rainforest. Each branch was mindfully selected, shaven, carved, washed, and placed. Care was expended in collecting leaves and boiling them to extract their tannins. Realistically, much like portions of the blackwater Rio Negro, the water is slightly murky. However, a shaft of light is able to shine through.

Animals: Symphysodon aequifasciatus, Paracheirodon axelrodi
Biotope description: Discus fishes are preparing to spawn. On the rainy season Amazonian biotopes are undergoing significant change: there is a high water. Clear water become unclear during that period. By May rains cease, within a few months there are many fully or partly isolated reservoirs. The slopes of the coast often steep enough, so even in the dry season there is a depth of 1-1.5 meters. Discus fishes live in such reservoirs and spawn between the flooded trees and coastal thickets. Along with them there are usually a variety of small tetras, catfishes and others.

Aquarium Age: 1 month
Animals: Chromaphyosemion bitaeniatum, Pantodon buchholzi, Pelvicachromis pulcher
Plants: Anubias barteri var. nana, Bolbitis heudelotii, Nymphaea micrantha
Biotope description: Ogun River empties into the Gulf of Guinea to the south-west from Nigeria. In the area of tropical rain forests, as we move towards the mouth, it absorbs forest streams and channels, forms a secluded backwaters, home to many species of fish. Seasonal flooding during the summer rains softens the water of the river basin, and pH also shifts to the acid, being a signal for the fish to spawn. The water temperature in the ever-shaded waters of tropical forests is often low (22-25°C). In slowly flowing streams and backwaters there are aquatic plants, ready to settle for a relatively small amount of light, among the roots of trees near the shore dwarf cichlids and non-seasonal killifish hide, under the leaves of water lilies there are Pantodons.

3. Congo

Jakub Kijak (Zegrze, Poland)
Aquarium Volume: 200 l
Aquarium Age: 1 month
Animals: Phenacogrammus interruptus, Pseudocrenilabrus nicholsi
Plants: Aquatic grass, Nymphaea lotus
Biotope description: The upper course of the Congo River, called the Lualaba, is a large, slow-flowing river. Large numbers of tributaries support a rich aquatic fauna. Over 150 fish species and 6 endemics are known from this region. Dominant families include Alestiidae, Cyprinidae, and Cichlidae. Lindi River is one of the smaller tributaries of Lualaba. The aquarium represents a calm bay just next to mouth of a Lindi River of Congo, near city of Kisangani in eastern Democratic Republic of the Congo. Both species (P. interruptus and P. nichlosi) can be found among others exactly there. River current isn’t as fast as upstream, so small group of Phenacogrammus interruptus can rest here. Big leaves of Nymphaea lotus make shadow zones. Female of Pseudocrenilabrus nicholsi is holding the brood. She can hide in mass of aquatic grass and make her fry safe. To imitate river dust I used dark river dust, so the bottom of the aquarium is mostly dark. My aquarium is high, so I decided not to fill it completely. It contains only about 100 liter of water. That gives better ratios of front glass.

Biotope description: The aquarium shows a cross-section of the rubble zone of Lake Malawi. In detail, it points to the location at which the gravel zone passes into the sand Zone. After I had seen numerous underwater photos of Lake Malawi, I have picked out the appropriate stone material. My choice fell on basalt rock. This is similar to the rocks of Lake Malawi and is therefore ideally suited. I have installed stones in different sizes from 60 kilograms to 50 grams. Right beginning I placed the stones almost to the water surface so there are many caves now. These stones fall off to the left into the sand zone. As substrate I used quartz sand of different grain. There are 125 kg total. The back wall is covered from the outside with a black film. Through this film a custom lighting gives a great depth. I have co-developed the light with a friend. It was made from programmable LEDs, we can adjust color and brightness of individual areas. This results in a very natural impression of the aquarium. Professionals like the light so much that we decided now to bring it to market. We have founded our start-up company. We have set the lighting so that all stones have an algae growth. The mbuna cichlids eat these algae very well. The volume of the aquarium is 1400 Liters. The aquarium is filtered by a Fluval FX5 and Eheim 2250. In addition, I use 3 flow pumps, each with a capacity of 8000 liters per hour. They are differently controlled by timers. I have also installed an automatic water change. With an automatic pouring machines I control the supply of fresh water. My biggest concern was to set up the aquarium as naturally as possible and thus to offer the fish a nice biotope.

Biotope description: The aquarium was set up based on Lake Malawi. Lake Malawi (Lake Nyasa, or Lago Niassa in Mozambique) is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. The third largest and second deepest lake in Africa, it is also the ninth largest in the world. It is home to more species of fish than any other lake, including about 1000 species of cichlids. The Mozambique portion of the lake was officially declared a reserve by the Government of Mozambique on June 10, 2011, and in Malawi a portion of the lake is included in the Lake Malawi National Park. Lake Malawi is a meromictic lake; permanent stratification and the oxic-anoxic boundary are maintained by moderately small chemical and thermal gradients. The water in Lake Malawi or Nyasa is typically slightly alkaline with a pH ranging from 7.7 to 8.6, a carbonate hardness of 107 to 142 mg/l, and a conductivity of 210 to 285 µS/cm. Given its tropical latitude, the water of this lake is generally warm, having a surface temperature that ranges from 24 to 29 degrees Celsius (75 to 84 degrees Fahrenheit), with a deep water temperature of about 22°C (72°F), year round.

9. Underwater forest of Congo river - Yangambi population

Emil Visan (Bucuresti, Romania)
Aquarium Volume: 200 l
Aquarium Age: 9 months
Animals: Pseudocrenilabrus nicholsi
Plants: Anubias barteri var. nana, Anubias coffeefolia, Bolbitis heudelotii
Biotope description: In this setup I tried to create a floodplain forest of the central flow of the Congo river inhabited by a colony of Pseudocrenilabrus nicholsi. A population Yangambi as was found by Gosse in 1963. This fish is found in Africa. More precisely, in the east of the central basin of the Congo River (the Ankoro and Upemba Lakes). Type locality for fish is Ankoro (at the junction of the rivers Lualaba and Luvua of Katanga Province, in the south-east of the Republic of Congo (formerly Zaire). Type of P. nicholsi location is outside the Congo Basin forest, but this species was also reported in the heart of central basin area of real rainforest. There are no data on the ecology of this species in the Ankoro, but Gosse (1963) has published this information about Yangambi populations. In this wooded area, P. nicholsi is found in small creeks, tributaries of the Congo River. These habitats are characterized by sandy substrate and detritus. Plants are few, but there are Anubias. On the clear areas of the water supply Bolbitis sp. can be found. Light is dimmed and filtered through the branches and roots. For this I used river sand 1-2 mm, African roots mopani and twigs of willow Torsa. At fixing them I used river stones and tried to make a submerged bank. I fixed on the roots and branches Anubias and Bolbitis, plants living in their natural habitat. For a background I used textil fabric of ocher colour. Pseudocrenilabrus nicholsi is a West African cichlid from the Congo basin (Riehl. etal., 2004). It was originally described as Paratilapia ventralis (Pellegrin, 1928). It has also been known as Haplochromis ventralis, Hemihaplochromis ventralis or Pseudocrenilabrus ventralis. P. nicholsi, is spectacular especially colorful male, that reach length of 8.5 cm. The female is smaller with about 5 cm and has more diluted colors. Males have a variety of colors. In general, the half of the face is bright yellow, which begins to change to blue for the back half of the body. The lips are bright blue. Unpaired fins are represented by red and blue. Pelvic fins are black, edged with white. Pectoral fins are yellow. Behind the gill cover to the back of the fish, there are red spots on the edges of flakes growing in numbers as you go further back on the fish. These cichlids are quite aggressive for their small size. They need to be kept in small groups with more females than males. They spawn quite readily in an aquarium. They spawn on the substrate or rocks. Females keep the eggs in mouth. The eggs are taken from the mother immediately after fertilization. Incubation lasts 2-3 weeks depending on the temperature and the fry is quite small. I needs very small food. The fishes are usually good mothers in the first week. The aquarium should have many places where females can hide. Males are aggressive towards females who do not respond to their advances. They live well at 22-25°C and pH of 6-8.

Aquarium Volume: 100 l
Aquarium Age: 1 month
Animals: Phoxinus czekanowskii, Pungitius sinensis, Barbatula toni
Plants: Fontinalis sp.
Biotope description: In the biotope aquarium there is a small tributary of the river Maihe (now Artyomovka). The river starts in the south-western slopes of the Przewalski Mountains (the southern part of the mountain range of the Sikhote-Alin) at an altitude of 460 m, flows in a southern direction and empties into the Gulf of Peter the Great Bay of Japan Sea. The water level in the river and its tributaries is highly dependent on the season, which is very typical for the mountain rivers of the South Ussuri region. When it rains a little, river becomes much shallower, small streams completely go under stones in places. This time the fish waits in deep pits. During the summer typhoon the water level could rise by 3-5 meters and then roaring stream carries uprooted huge trees. The biotope you see is a typical mountain taiga stream, characteristic inhabitants of which are small fishes that love fast and clean, oxygenated water: common minnow (Phoxinus phoxinus) and Lagovsky minnow (P. lagowskii), Amur stickleback (Pungitius sinensis), Siberian stone loach (Barbatula toni) etc. However, there are also large predators such as sharp-snouted lenok (Brachymystax lenok) and resident form of masu salmon (Oncorhynchus masou). Aquatic vegetation is represented only by moss Fontinalis. Partially rounded stones, among which red lava is not uncommon, large driftwood and fallen trees are typical scenery of the stream.

But the area where dwarf rainbowfish can be found in nature is very small: a small part of the river Mamberamo flowing through one of the provinces of Papua New Guinea. In 1998, they were also collected in small streams and swampy waters of the river Tiroiva. These specimens differ from the representatives from Mamberamo by having horizontal red stripes between the rows of scales. Dwarf rainbowfish can be found not only in the fast streams of the main river, but also in the surrounding wetlands with slow current, where there are many aquatic plants, driftwood and submerged roots of coastal plants, and this entry presents such a habitat.

Plants: Microsorum pteropus, Microsorum sp., Nymphaea sp., Cryptocoryne ciliata, Cyperus helferi
Biotope description: The aquarium was set up based on a rainforest stream of Warey River on Batanta Island, New Guinea. Batanta is one of Raja Ampat Islands, and lies 36 km from Sorong near the western end of New Guinea. The island is long (61 km), slender (averaging less than 10 km in width) and mountainous with a maximum elevation of about 1,050 m. It is separated from Salawati by the Sagewin Strait, which averages only 5 km in width, but has impressive depths to 521 m. The southern Salawati-facing slopes are steep and drained by numerous small, steep gradient creeks, but no rainbowfishes occur there. The opposite side of the island is also steep, but is dissected by a few gradual valleys. M. synergos have been collected from the Wei Bin (type locality) and Warey River, at the respective eastern and western ends of the island. Warey River consists of narrow clear rivers with gradual gradients flowing initially through second growth forest, but entering primary, nearly closed canopy forest after about 1 km upstream from the sea. The substrate of the river consist from sand and limestone cobble-gravel. Temperature and pH values of 25.5°C and 7.8 respectively were recorded at the type locality. In this case I represent a rainforest creek into the river where are mainly found Melanotaenias synergos around submerged logs and aquatic plants. This species was first collected in 1992 by Heiko Bleher while exploring the freshwaters of Batanta Island.
