A customer left this guy at my lfs and it's stuffed into a 20 long that's 75% filled with plants. He's about 7" and has been in there for over a month and I'm tired of seeing him suffer so I've decided I'm gonna rescue him. Before I do I just want to find out which of my tanks he should be in, what to expect from size etc. Also, I know they're schooling fish so I would like to get him some companions. Obviously, to know all of this I need to know which of the two tinfoil barb species he is (redtail tinfoil or tinfoil). To me his head looks like a tinfoil barb but I keep reading that the tinfoils have distinct black lines on their tail, and this guy doesn't. Any help with the ID would be appreciated. I know the pic isn't great, but he doesn't move at all because he has nowhere to go in this tank.
