don't plan on seeing him very often. mine hangs out in between my rocks and back glass and doesn't so much as stick his head out unless there is food on a stick in front of him. otherwise, he is a very neat fish. extremely cool-looking. he will, however, eat anyhting that will fit in his mouth. much like a lion. quite aggressive towards tankmates at feeding time, but for the most part keeps to himself. he's about 6-7" right now. i hope he stays alive for a long time.
