Thanks for all the help! My little guys are doing great and I find myself just staring at them for long periods of time. There are two of them which are bigger than the rest, are those females or just adults in comparison to the other 5 which are about the same size.
The only thing I'd watch out for (if they're wild caught) are intestinal worms, which are usually pretty noticeable. I've received several cory cats with them, but only wild caught strains. (Adolpho's, Julii's, etc.)
