Bedotia geayi
SYN
: None
PD
: An elongated, laterally compressed species with a pointed head and a rounded, fan-like caudal fin. There bare two dorsal fins; the first very short, while the second is much longer. The anal fin is long running from the mid-belly region to the caudal fin. The back is usually yellow-brown and the flanks are marked with a broad,bluish band. Another parallel band runs near the belly, although is less intense. The flanks have a silvery to green iridescence. The anal and second dorsal fins are orange-yellow with a black or red border. The caudal fin is white to black with black along the edges. The outmost parts of the caudal fin may be blood red.
SIZE
: To 6" (15 cm)
SS
: None
HAB
: Inhabits mountain streams in Madagascar.
S: middle, top
TANK
: A tank measuring 36" (91 cm) with a capacity from 35-45 gallons (132-170 L) is suggested for young fish. Adults require a 48" (122 cm) tank. Leave large open swimming areas and plant along the back and edges of the tank. Suggest bright lighting and a moderate to strong current.
WATER
: pH 7-8 (7.0), 10-18 dH (10), 68-75°F (20-24°C)
SB
: An active, schooling species suitable for a community tank. This species must be kept in groups of at least four fish.
SC
:
Glossolepis, Melanotaenia, Corydoras,
Danios
FOOD
: Live; insect larvae, worms, crustaceans, insects; flakes; pellets; spinach.
SEX: Males are conspicuously more colorful with a pointed first dorsal fin.
B
: Use water with values suggested above and make frequent partial water changes. The tank should measure at least 28" (71 cm) and have some circulation. A small number of brown eggs are laid daily among fine-leafed plants and are attached by threads. The pair spawns continuously over a period of months. The eggs hatch after six to seven days and the fry first feed on roftiers and paramecia. Later the young can be fed with
Artemia
nauplii. Both the eggs and the fry are ignored by the parents. The fry swim in an oblique position at first, but soon develop normal swimming habits.
BP
: 7. Breeding is moderately difficult and the young may be sensitive to water conditions.
R
: The Madagascar Rainbowfish requires clear, clean water.
DC
: 6. This peaceful species is sensitive to water pollution and requires frequent partial water changes to thrive and keep its delightful colors.

Using fish as livestock feed threatens global fisheries
(11/18/2009)
Fish doesn't just feed humans. Millions of tons of fish are fed every year to chickens, pigs, and even farmed fish even in the midst of rising concerns over fish stocks collapses around the world. Finding an alternative to fish as livestock feed would go a long way toward preventing the collapse of fish populations worldwide according to a new paper in Oryx.
ICCAT fails to protect critically endangered tuna—again
(11/15/2009)
The International Commissions for the Conservation of Atlantic Tuna (ICCAT) ignored the advice of its scientists to end fishing of the Atlantic bluefin tuna. Instead ICAAT set a quota of 13,500 tons of fish. This is not the first time ICCAT has flouted its own researchers' advice: it has repeatedly set quotas well-above its researchers' recommendations.
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.
