I kept a few 5 years ago in a tank I threw tons of Wisteria to float in for cover. With starving I was able to get them to take frozen mysis and brine shrimp and if I remember rightly I think I may have gotten mine to take flake as well but they never even looked at pellets, just sank to the bottom. Never tried keeping them with tankmates either but as noted above females can be quite mean to males.
