I had a couple of those guys and thought about raising them but with no success! They can't stand alot of current in your tank as they can easily be sucked up in your powerheads and over flows and I ended up putting mine in my reef tank and never saw them again! May have been because I had a puffer at the time! Got them for the same reason---AIPTASIA!!! Ended up getting peppermint shrimp and a copperband butterfly and no more aiptasia!!
