Cyprinds / Flying Fox

Flying Fox
Epalzeorhynchus kallopterus | Pictures

Synonyms: Barbus kallopterus
Physical description: An elongated fish with a flat belly profile.   The back is olive brown to dark brown while the lower-parts are yellowish white. A brown-black, lateral stripe extends from the snout, through the eye, and to the fork of the caudal fin. Above this is a more slender, gold stripe.   The dorsal, anal, and ventral fins have a black band and a white edging. The iris of the eye may be bright red.
Size/Length: To 6" (15 cm), although rarely larger than 4.7" (12 cm) in aquaria.
Similar species: Siamese Flying Fox ( C. siamensis)
Habitat: Inhabits fast-flowing streams and rivers in foothill areas.   Southeast Asia; Borneo, Java, Sumatra.
S: bottom
Aquarium: A 32" (81 cm) tank with a capacity of 30 gallons (114 L) is adequate for fish smaller than 4" (10 cm). Fish larger than this must be kept in a tank measuring at least 36" (91 cm) with a capacity of 35 gallons (132 L). The tank should be heavily planted and have a moderate to strong current.   Provide hiding places with rocks, roots, and wood and use strong lighting to promote algae growth.   Use a fine gravel substrate.  
Water chemistry: pH 6-7.5 (6.5), 2-12 dH (6), 73-81°F (23-27°C).   
Social behavior: The Flying Fox should be kept singly or in schools.   If kept in small groups, territorial disputes quickly arise. Peaceful towards dissimilar species, the flying fox is recommended as an algae eater for a community tank.
Suggested companions: Gouramis, Danios, Barbs, Loaches, Acaras, Angelfish, Eartheaters, tetras, Rasboras, Knifefish.
FOOD: Algae, vegetable flakes, vegetables; spinach, lettuce; tablets; oatmeal; live; planarias, Tubifex , crustaceans; aquatic insets.
SEX: Unknown
Breeding techniques: Unknown
Breeding potential: 10. No spawnings in captivity have been reported.
Remarks: This species will not eat Thread Algae.   This species has a habit of resting propped up by its pectoral fins.
Difficulty of care: 3. The Flying Fox is a decent algae eater that can be easily kept in a community tank.   Suggest partial water changes two or three times a month to keep this fish in good health.

Overfishing may hurt Amazon forest trees
(2/5/2008) Overfishing is reducing the effectiveness of seed dispersal by fish in the Brazilian Pantanal, reports Nature. The research suggests that fishing practices can affect forest health.

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.

How to save the world's oceans from overfishing
(7/8/2007) Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Despite these dire trends, the situation is changing. Today some of the world's largest environmental groups are focused on addressing the health of marine life and oceans, while sustainable fisheries management is at the top of the agenda for intergovenmental bodies. At the forefront of these efforts is Mike Sutton, director of the Monterey Bay Aquarium's conservation program: the Center for the Future of the Oceans. The aquarium, which has long been recognized as one of the world's most important marine research facilities, is pioneering new strategies for protecting the planet's oceans. Sutton says the approach has four parts: establishing new marine protected areas, pushing for ocean policy reform, promoting sustainable seafood, and protecting wildlife and marine ecosystems.
