The last time the piranhas were small. The Black rhoms where 3" to 4" and the red belly about 4". The tank was only a 4' 45 gallon if I remember correct as it was about 14yrs ago. It wasn't planted and had caves constructed from slate. The new experiment is in a 180 gallon and the Rhoms are 8 1/2" and 6" and the Reds are 6". It's been about 18 days and just a couple of reds have bit fins and no deaths. Rhoms have their fins intact. The tank is heavily decorated with 3 caves. They are currently all eating smelts.ballinouttacntrol;4305231; said:Can i get more info about your previous experiment? How big were they? How big was the tank? Planted?
