Okay, so I got myself a new friend today. Happens to be pretty sick with fin rot, So I am going to try to nurse him back to health, if he pulls through, and doesn't die from some mishap, I would like to get him in a communal tank.
The lady at Walmart in which I obtained this little fellow said that he was aggressive, but they put him in a tank filled with tiger barbs, which they are aggressive, tend to bite at other fishes tails. (My girlfriend male sword tail got his tail ripped off by one.) Pretty sure he lost a lot of his fins by that as well. I assume he got aggressive from them attacking him.
As I was saying though, I would like to put him in a communal tank, but I want to try to get him used to other fish around him before I actually do that. So are there any fish, that are cheap, can stand tropical heat, and can be used as testers. I'm thinking Guppies I think they stay in the 76-78 degree heat but I don't know.
