Northern Madagascar Biotope Aquarium Setup
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.

Malagasy Crayfish
According to Bradt 2001, six species of crayfish have been described in Madagascar, all of which are endemic. What makes this occurrence particularly interesting is crayfish are not present in Africa or India -- meaning Malagasy crayfish may have much older origins. Today crayfish are a vital source of protein to many in Madagascar.

Northern Madagascar Biotope Aquarium Setup
Ankarana Dry Forest Stream
++++++++++++++++++++++++++++++
Madagascar's fish species are some of the most threatened on the planet. Habitat loss -- especially the conversion of native vegetation to rice paddies -- combined with horrendous erosion resulting from deforestation and the introduction of exotic species (especially Tilapia, Snakeheads, Mosquito fish) have devastated endemic species. Several of Madagascar's unique species are no longer recorded in the wild. The plight of Madagascar's fish species mirrors the degradation of its terrestrial habitats.
One of the most beautiful aquatic habitats I have ever seen was in Ankarana -- a stretch of dry forest in Northern Madagascar. The creek was shaded by a high canopy but richly endowed with gorgeous aquatic plants (shafts of sunglight penetrated the canopy). The substrate was fine sand and the banks of the stream were packed earth. At the time I didn't pay too much attention to the fish or aquatic vegetation as I was focused on the remarkable crowned lemurs and fascinating reptiles found nearby.
Sadly I do not have any pictures of this magnificent habitat -- it was among the rolls of film that got destroyed over the course of a very rough trip.

WATER:
pH: 7.0-8.0, 8-19 dH, 75-84 F (24-29 C)
TANK:
Use silica (silver) or very fine gravel for the substrate. Lighting can be bright and the tank should be heavily planted. Driftwood can be used as desired. The water should be clear and have a slow to moderate current.
PLANTS:
The following plants are among those found in Madagascar: Aponogeton boivinianus, Aponogeton longiplumulosus, Aponogeton Madagascariensis [the plant has been so sought after that is have been depleted over its natural range (care tips, more info)], Aponogeton ulvaceus, Lagarosiphon Madagascariensis, Bacopa Madagascariensis, Hydrotriche hottoniifloria, Blyxa aubertii, and Cyperus alternifolius
FISH:
Rainbowfish
Bedotia geayi - Madagascar Rainbowfish, Red-tailed Silverside. "Occurs in coastal rivers, up to an altitude of 500 m" (Fishbase)
Rheocles sp.
Cichlids
Paretroplus (Lamena) nourissati
Paretroplus (Lamena) damii
Paretroplus (Lamena) kieneri
Paretroplus (Lamena) maculatus

Killifish

Pachypanchax omalonotus (Fishbase)
Gobies
Gobies are fairly comon in freshwater, brackish water, and marine habitats throughout Madagascar.

Tropical ocean dead zones could increase 50 percent by 2050
(11/18/2008) If carbon dioxide levels continue to rise as expected, marine dead zones in the tropics are expected to increase by 50 percent in just over four decades, according to a new study from the Leibniz Institute of Marine Sciences in Germany. The expansion of marine dead zones in tropical seas could have devastating impacts on ocean ecosystems and fisheries.
Monstrous Chinook salmon found in California
(11/14/2008) A fifty-one inch long Chinook salmon, found dead during a salmon survey in Battle Creek by the Department of Fish and Game (DFG), is probably a record for the state of California say Department biologists.
Hundreds of rare and bizarre marine species discovered
(11/9/2008) The evolutionary origin of deep sea octopuses, new species populating an underwater "continent", 12,000 amphipods crowding a square meter in the Gulf of Mexico, massive gatherings of white sharks in the middle of the Pacific: these are just a few highlights from the Census of Marine Life (COML)'s fourth report.
One-third of global marine catch used as livestock feed
(10/30/2008) Despite continuous warnings of emptying oceans due to overfishing, a new report finds that one-third of the world’s total marine catch is not feeding humans, but livestock. The fish are ground-up into meal and fed to pigs, poultry, and even farm-raised fish.
U.S. pledges $40M toward coral reef conservation.
(10/22/2008) The U.S. government has pledged almost $40 million to protect biologically-rich coral reefs in Southeast Asia, according to the U.S. embassy in the Philippines.
