Serrasalmus eigenmanni (Norman, 1929)
Black Ear Piranha
South America: Brazil, Venezuela, French Guiana, Surinam, Guyana.
The maximum size of the Eigenmann's Piranha is around 20cm. (8"), although in captivity most specimen grow little over 15cm. (6") in size.
- Clear eyes.
- Clearly visible humeral spot.
- V-type caudal fin.
- Concave head shape.
Adult fish need a tank of at least 48x18x18", while younger specimen can temporarily be kept in smaller tanks, the minimum being a tank of 32x14".
The aquarium needs to be decorated with plants, (drift)wood and rocks to provide hiding places for this often somewhat shy and skittish fish (especially during the first weeks/months). But an open area to swim should also be offered. A powerhead can be used to add a little extra water currents, to mimic its natural habitat.
None. Because of its fin-nipping habit and intolerance towards other tank mates, this species should be kept alone in a species tank. In some rare cases, a Pleco, Raphael Catfish or other heavily armed catfish worked out.
