The Sanchez' Piranha is one of the few Serrasalmus-species that has been succesfully kept in a group, despite the fact that is is not very tolerant towards tank mates, and in particular its own kind. However, due to it's parasitic lifestyle (scale-eater, fin-nipper) and agressive character, these are rare occurences, and attempts are usually shortlived. All in all, it is best to keep this species as a solitary fish: attempting to shoal this species is only recommended to very experienced piranha keepers!
Η "φαγωμάρα" μεταξύ τους είναι φυσιολογική συμπεριφορά την οποία ΔΕΝ πρόκειται να δείς σε 70 λίτρα με 2 ψάρια. Το πολύ πολύ να "την πληρώσει" το ένα απο τα 2...
Εύχομαι να έχεις την ευκαιρία να τα καμαρώσεις σε 1000άρι όπου θα μπορείς να βάλεις 8-10 και να θεωρείσαι "very experienced piranha keeper"...
