BIOTOPE AQUARIA
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.

Central
America has several great lakes like Atitlan, Managua, and Nicaragua.
The lakes are rocky with hard, alkaline water.
The cichlids in these lakes are generally very territorial and aggressive and should not be combined
in the same with peaceful species such as livebearers.
WATER:
7.5-8.2, 15-25 dH, 75-81 F (24-27 C)
TANK:
The tank should be furnished with large, sturdy rock structures.
The substrate can be fine gravel or sand.
There should be little water current.
PLANTS:
There are few plants in these lakes due to the hard water.
In the aquarium, live plants will be destroyed by the cichlids.
FISH:
Loricarids, Pimelodids, Livebearers, lake Cichlasomines.

Recent news
Mediterranean bluefin tuna originate in the Gulf of Mexico
(10/2/2008) Researchers have discovered a previously unknown migratory route for the northern bluefin tuna, proving for the first time that the species' Mediterranean and North American subpopulations interact. According to the paper published in Science the two groups meet as juveniles then return to their birthplace to spawn. For a critically-endangered species that is still heavily fished, the new finding has large conservation and management implications.
12 fish species go extinct in lake near Istanbul
(9/24/2008) Turkey has lost twelve species of fish to pollution in Lake Sapanca. Lake Sapanca used to be one of Turkey's most bio-diverse lakes. A decade ago the lake's water was pristine enough to be pumped directly to Istanbul for citizen use, but due to rising pollution it no longer serves as a source for the city water.
100 new species of sharks and rays discovered in Australia
(9/19/2008) Scientists have described 100 new species of sharks and rays in the seas around Australia.
A solution to worldwide fishery collapse?
(9/18/2008) In November 2006 a study on global fisheries received a lot of attention: employing 53 years worth of fishery data, Boris Worm predicted that by 2048 the ocean would be empty of fish. Essentially there would be nothing left to catch. Already, Worm reported, fishing stocks had collapsed in 29 percent of the world's fisheries. Although scientists called for rapid and overhauling changes to fisheries, the fishing industry carried on business-as-usual. Now, two years later, a study in Science proposes to have found the solution to the global fishery-collapse.
Nearly 40 percent of America’s freshwater fish in danger
(9/10/2008) The most comprehensive study of America’s freshwater fish in twenty years has revealed that nearly 40 percent are threatened with extinction.
