I'm just suprised my 6" jd isn't running the tank. Hes probably the most mellow fish of all. He's 2+ years old so I know he/she is full grown.
On another note, I was looking at my 30g tank earlier and my old convict is all beat up. I don't think it was from anybody in the 30g but from the convicts I had him with in the 20g two days ago. I feel bad for him, hes been the homliest looking fish ever since I've had him. Right now his fins are all cut up, and he has patches of white all over him but it doesn't look like ick. I'm just assuming thats where he got beat up and thats what it looks like when its healing. I will post some picks later. For now I raised the temperature in the tank, added some more salt, and some stress coat.
