The Spilopleura 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
all in all i would say dont go for it ..not that experienced then dont even try just gonna coast ya...try the ternetzi piranha they are aslo yellow and gold in color and they belong to the pygo group and therefore easier to group up
