I have never owned one my self, but I talked at length with someone who did. It was one of those instances where the guys girlfriend went to the pet store by her self and they just bagged the fish up for her with out telling her anything about the fish. The thing was a terror, and a tiny one at that. They eventually gave him away, its like Im getting dejavu all over again in this thread. Personally, I would get rid of the fish. He will seriously limit your corals/fish selections, and to me thats not as much fun as being able to buy what ever you want. Besides, if you do keep him then you wont be able to fill up your tank with what ever corals you want to prepare yourself for the upgrade, because theres no excuse to upgrade if you still have room in your exsisting tank. and when you do get your tank upgrade you can make your 58g a mini predator tank, where you can throw all kinds of mayhem in and not have to worry because youve dedicated your tank to that sort of thing. So in short: take the fish back to texas tropical and have a discussion with them as to why they even keep this sort of animal in their stock in the first place because its irrisponsible and expensive (based on livestock you lose) to you as a hobbiest.
