Hey folks. I just came upon this website tonight and I am fired up!!! Nice to meet everyone. There is great info on here and I'm glad to have came across it. I used to have 3 rb's in a 55 back in 1996 and I broke the piranha fever and haven't thought about them since. Well, that was until 3 weeks ago when I set up my tank and just yesterday I purchased a 4 inch black rhom. He's still pretty shy but a beautiful little guy. About after how many inches do their eyes turn red? When do they start getting pissed off? When they're a little bigger? I'm really looking forward to getting back into keeping these kick ass fish. Thanks for your help!!! :laughlong:
