of large rivers.

Columbia and Venezuela; Rio Meta and its tributaries.
S: bottom, middle
Aquarium: 40" (100 cm) or 45-55 gallons (170-209 L).
The tank should be well-planted with
robust plants and have a cover of floating plants to diffuse the lighting.
Leave large, open swimming areas and
use a powerful filter that creates strong current.
The substrate should be fine gravel or sand.
Provide hiding places with roots, caves,
and wood.
Water chemistry: pH 6-7.5 (7.2); 4-15 dH (10); 68-82°F (20-28°C)
Social behavior: A group fish that gets along well with large community fish, such as Angels or other
Cichlids.
Smaller fish will be eaten by this nocturnal predator.
Suggested companions: Central and South American cichlids, large characins, Arawana.
FOOD: Live; earthworms, fish,
Tubifex, insect larvae; tablets; chopped
meat.
SEX: Females are plumper and larger than males.
Breeding techniques: Unsuccessful, possibly because fish do not reach maturity in aquaria.
Breeding potential: 10.
Breeding has not been recorded in captivity.
Remarks: Suffers from lack of exercise in small tanks. With their long barbels, they "taste"
the bottom of the tank in search of fallen food. The Pictus Cat has very sharp spines that easily get caught in
a net. Do not handle these fish, these spines can pierce the skin.
Difficulty of care: 4.
A hardy catfish that requires an occasional feeding of live foods.

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.
