I have had terrible success with these. They are suseptible to dying from medications, water changes, and temperature fluctuations. They do/can get along with other fish, african cichlids, barbs. They prefer live worms but can be coaxed into frozen. I am a very experienced mfker and have sadly lost more than a handful. The wife forbids me to get another one but they are so dang cool! I wish you better luck than i have had.
