Serrasalmus sanchezi

Serrasalmus sanchezi, while resembling other piranhas, is unique in their solitary or small-group behavior compared to larger shoals seen in other species. Known for their aggression, it's advisable to house them in a species-only tank. Their diet should consist of meat-based foods to replicate their natural feeding habits in the wild. Maintaining water quality with regular changes and filtration is key to preventing common fish illnesses.
