CATFISH
SCHILBEIDAE FAMILY
The Schilbeidae or Glass Catfish Family is found throughout Africa and Asia and includes the genera Eutropiellus, Parailia, and Schilbe. About 45 species are
included in this family. [the Glass Catfish from Southeast Asia]
Flag-tailed Glass catfish, African Glass Catfish[Pictures]
Eutropiellus buffei
SYN: Eutropius buffei, Eutropiellus vanderweyeri
PD: This catfish is elongated and has a distinctive, wide longitudinal black line that extends the length of the body. It has three pair of barbels and its dorsal fin is
tall. The body coloring is white to blue and somewhat translucent. There are two other stripes that become more pronounced with age. One extends along the top
of the back, while the other along the belly. In reflected light sometimes parts of this fish are gold to red. The African Glass Catfish has a long anal fin that is
deeply forked. Its eyes are large while the mouth is small. The fins are transparent.
SIZE: To 3.2" (8 cm)
SS: A similar species, Eutropiellus debauwi, from Malebo Pool (part of Stanley Pool, Zaire) can be distinguished by its rounded tips on the caudal fins. E.
debauwi is rarely seen.
HAB: Near riverbanks in floodplains. Central Africa: Southern Nigeria; Niger River watershed
S: middle
TANK: 32" (80 cm) or 30 gallons (114 l). Provide well-planted corners for retreats. The tank should have dim lighting caused by a cover of floating plants.
The tank should be arranged in dark colors to help comfort the fish. Use a filter that provides strong current and leave open swimming areas.
WATER: pH 6-7.5 (6.8), 1-16 dH (7), 75-82°F (24-28°C)
SB: A peaceful, schooling fish that can be kept in a community tank. Keep in groups of at least six or more individuals. Single fish do poorly.
SC: Synodontis, Congo Tetras, Kribensis, Steatocranus
FOOD: Live; insect larvae, Tubifex, Brine Shrimp; flake.
SEX: Females are plumper
B: Stimulating the rainy season helps initiate spawning. Keep one male with two females. Up to 100, white eggs are laid among plants and they hatch in 2-5
days. The parents should be removed after eggs are laid. Fry are difficult to raise, try feeding them small live foods like Artemia. Once fry are established, they
grow quickly.
BP: 9. Breeding this catfish is very difficult.
R: This fish may nibble plants if not fed sufficient amounts of food. This fish's caudal fin is constantly moving, when resting or swimming. This fish may get
caught in a net because of spines on the dorsal and pectoral fins. Instead, use a glass or plastic bag to catch this catfish. This species was formally known as E.
vanderweyeri. Regular water changes are needed to keep this catfish in top condition.
DC: 4. A pleasant fish that requires a diet supplemented with live foods.
African Glass Catfish, Congo Glass Catfish
Parailia congica
SYN: Parailia longifilis
PD: Its body is elongated and laterally compressed. It is scaleless and lack body pigment, thus making the fish semi-transparent. The body color is light brown
and small brown spots cover the body. The internal organs and backbone can be seen. A dark brown stripe runs the vertebrate and extends to the tip of the tail.
A line of small spots runs along the bottom part of the fish's body. A long pair of barbels are located on the upper jaw, while two slightly shorter pairs and one
small pair are located on the lower. This glass catfish lacks dorsal and adipose fins.
SIZE: To 3" (8 cm)
SS: Kryptopterus, Omnpok, Parailia
HAB: West Africa; Stanley Pool of the Zaire River.
S: bottom, middle
TANK: 32" (80 cm) or 30 gallons (114 L). Provide good aeration and moderate current. The water should be very clean and clear. The tank should be
well-planted. Provide hiding places with rocks, roots, and wood.
WATER: pH 6.5 to 7.5 (6.9), 2-15 dH (8), 73-79°F (23-26°C)
SB: A shy, peaceful community fish that should be kept in a shoal of at least four fish. Individual specimen do poorly. A diurnal catfish.
SC: Synodontis, Congo Tetras, Kribensis, Steatocranus, Eutropiellus, tetras
FOOD: Live; insect larvae, Brine Shrimp, Tubifex, aquatic and terrestrial insects; flake. This fish must be fed live foods 1-2 times a week to stay healthy.
SEX: Females are said to be plumper.
B: Has not been reported. By feeding a pair mosquito larvae and Daphnia, keeping them in a clean tank, and stimulating the rainy season; spawning should be
possible.
BP: 10. Breeding has not been accomplished in aquaria
R: Very sensitive to water pollutants. Perform frequent partial water changes.
DC: 5. A sensitive fish that requires a diet of live foods.

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.
