Hello all, im new to the board. Ive been reading everything on this board for a while...its the reason i have piranhas. I have one red belly piranha about 2'' and just got a Rhom that is about 2.5-3''. I actually wanted to get an elongatus, but i just found my Rhom at a great lfs about 2 weeks ago. I love him already. He is getting used to me pretty quickly. I have some decent pics of him. He is currently in a 55 gallon with a tetra tec pf500 filter and i also have a power head. I unfortunately got a weak model b/c when i bought it i was thinking the number on it meant the flow rate like some do, but it didnt. So that power head will go to the red belly and im going to get one that flows 300gph for him.
