Out of the dozen or so pet shops here only 2 carry piranha. Well I sell babies to one of them, the other gets his from another guy by here.well I stop in at both regularly anyhow today I was at the one that doesn't sell mine n I've noticed this for months now but he has a dozen or so of rbp that were hatched right by new years well these fish are at the very most silver dollar sized!even today still that size! When he 1st got them they were nickle maybe quarter at most!maybe they mini rbp? 6 almost 7 months old n still dinky!I've raised 10 batches bigger than his n I started 2 months later! Anyone heard of piranha being that stunted that small?its no wonder he's barely sold any in 5months! N his are cheaper than the one that sells mine! Lol
