I have a 40 gallon breeder that I'm going to be redoing once I move into my new place. AquaScape just got some more Red Wolf Fish in and also has a sale on red belly piranhas right now.. Could I do 3 RBP (is 3 the very max i could have) or just one Wolf? Which would be better? I would like something predator like and fun to watch in my living room. I would have 2 good filters going too and all that good stuff lol. I was just wondering what some of your thoughts are!
