I have a 30 gal community tank and a 10 gal tank that I was going to put some convicts in at a buddy's request (he's got an oscar and wants the free food). So I went to the lfs and bought three of them, two males and one female. this was at the lfs's reccomendation, saying they work best in groups of three or more and that three would be fine. well, after seeing these forums, she's on smack, and after seeing the two who obviously are 'pairing' up tag on the odd man out, I need to put him somewhere. I thought about putting him in my 30 gal community tank. will he be safe there? or better yet, will the OTHER fish be safe with him in there?
