I think they'd be OK. In the Baensch Atlas they are said to prefer 21-25C which is 70-77F. You'd be on the top part of the scale, but not too badly over. I've kept fish in warmer than preferable water and they lost weight quickly due to increased metabolism, so you may want to watch for that. Otherwise, sounds like a fun fish to keep, they're always sick when they come into my LFS and I've never gotten to try them. GL!
