Single red bellied piranha tank mates?

[Deadliestviper7]

Single redbellies are much different than schools, personally why not keep the runt with a mix of larger silver dollars, pacu and maybe some wimples.

(Note there will likely be fin nipping)

tlindsey is bang on. first to go will be the Oscars tails. then the fins. then the eye balls. the scales etc. u get the picture

Jesus, sounds like a bad horror film haha, cheers for the advice everyone, I knew it would be a no no, just got lured in by seeing other people do it, think I'll just put a tank divider in the tank till she catches up to the rest of them
