The species of the genus Brycon belong to the large tetras of the open water. 21 species east of the Andes were distinguished in the last revision by Flávio C. T. Lima (there are others west of the Andes). Their identification, especially of juveniles, presents considerable difficulties, because they usually grow to 30-40 cm in length and adults look quite different from juveniles. That is why we listed B. amazonicus as Brycon sp. Colombia on our stocklist until now. However, the fine line pattern of the juveniles, which is very unusual for Brycon species, and the distinctive caudal fin pattern now lead us to believe that these animals are the species B. amazonicus, which is widely distributed in the Amazon and Orinoco systems.
The care of Brycon is in principle simple, but one must not save on food. They are very greedy and fight for a food tablet like a pack of puppies for a bone. Due to their expected final size (approx. 50 cm!), combined with swimming pleasure they need large aquariums.
For our customers: the animals have code 212652 on our stocklist. Please note that we only supply wholesale.
