BIOTOPE AQUARIA -- Southern African Swamp
A biotope aquaria is an aquarium that is set-up to simulate a natural habitat. The fish, plants, water chemistry, and furnishings are similar to those that can be found in a specific natural setting.
Always check compatibility! Some species from a particular habitat are not suitable tankmates. For example, the Peacock Bass will eat small tetras since they are their natural food in the wild.
The biotope aquarium can be adapted by adding species from disparate areas that have similar water requirements.

The Okavango Delta is among the largest swamps in Africa. The waters support a variety of species and vigorous plant growth making it an ideal subject for a biotope aquarium.

Reedy plants line the shores of waterways and shallow pools. Floating grasses and lilies are found where there is little current. Banks along moving waterways drop off quickly, creating cliff-like formations with overhanging roots. Many fish seek refuge under these root overhangs and inside caves.
WATER:
pH 7.2-7.8, 2-8 dH, 70-75 F (21-24 C)
TANK:
The tank should have fine gravel, sand, or clay for a substrate.
Plant grassy vegetation along with rear and corners of the tank. Use dense leafy vegetation in the center of the aquarium and scattered floating plants (if desired).
Use submerged wood to provide hiding places akin to those created by overhanging roots and clay caves in the natural setting.
The lighting should be bright and the water should be clear. Current should be still to moderate depending on whether the aquariast is amining to recreate a still pool or flowing channel.
PLANTS:
African Water Fern, Ammannia, Marsilea, Eleocharis, Anubias, Nymphaea, Water Lettuce
FISH:
Mormyrids, African tetras, barbs, spiny eels,
Haplochromines, Tilapia, Hemichromis, Synodontis, Clarias catfish.
In the neighboring floodplain, annual Killifish can be found.

Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012)
The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012)
South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012)
A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
Bycatch-reducing fish trap wins $20,000
(01/11/2012)
An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
World's most expensive tuna
(01/05/2012)
A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
Top 10 Environmental Stories of 2011
(12/22/2011)
Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
