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.

Governments, public failing to save world's species
(11/04/2009)
According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
Atlantic bluefin tuna should be banned internationally: ICCAT scientists
(10/29/2009)
Scientists with the International Commission for the Conservation of Atlantic Tuna (ICCAT) have said in a new report that a global ban on Atlantic bluefin tuna fishing is justified. ICCAT meets in November to decide if they will follow their scientist's recommendations.
The Yangtze River may have lost another inhabitant: the Chinese paddlefish
(10/22/2009)
In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.
Freshwater species worse off than land or marine
(10/15/2009)
Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
New species of ghostshark discovered off California's coast
(09/22/2009)
The discovery of Eastern Pacific black ghostshark Hydrolagus melanophasma is notable for a number of reasons. It is the first new species of cartilaginous fish—i.e fish whose skeletons are made entirely of cartilage, such as sharks, rays, and skate—to be described in California water since 1947. It is also a representative of an ancient and little-known group of fish.
Photos: new deep sea species discovered off the Canary Islands
(09/21/2009)
Owned by Spain, but located just off the northwest coast of Africa, the Canary Islands sport a wide variety of marine life, including five species of marine turtles, ten species of sharks and rays, and innumerable fish and invertebrates. However, a new expedition has gone beyond the known, sending a robot to depths of 500 meters to discover the secrets of the Canary Island's deep sea.
