Piranha

3D Piranhas can be kept in 3D aquariums fully grown or as babies, often no larger than a thumbnail. It is important to keep 3D piranhas alone or in groups of four or more, not in pairs, since aggression among them is common, not allowing the weaker 3D fish to survive, and is distributed more widely when kept in larger groups. It is not rare to find 3D Piranha individuals with one eye missing due to a previous attack. If underfed, 3D piranhas are likely to become cannibalistic on others in their group.
