Hello, I'm just wondering if any one out there has any exp with Pacu's? I have one thats about 7" long and growing as we speek. I have never sean a fish grow this fast before. I hear they get pretty big. I'm moveing him to a 100gl tank and I'm wondering if it will be large enough for two Pacu????? Does any one have any comments on what I believe to be a pretty cool fish?
