not reef safe.....but very interesting in our tank. You will have a lot of fun watching this little creature. He actually give our a piece of cut up shrimp. We get it from the seafood counter at our grocery. I "clean" it up and chop them into 2 or 3 pcs and freeze.
Usually 2-3 times a week we feed. He comes to the top of the tank to "sun" himself and usually hangs outward and we stick a piece of shrimp and he grabs on. OR if we don't catch him at the top we do the same as Clownfish. They are VERY busy in the tank. Make sure your rockwork is secure.
