I put him in half of a seperated 100g tank. I stacked about 15 pounds of LR in with him. I have a 3" sandbed and I put a pile of bigger chunks of CC. He just sat there all day yesterday, today he has been grabbing big pieces of crushed coral and filling in openings to his hideout. He is by far the most interesting creature Ive had in my tanks so far. I fed him a goldfish last night and he was a little slow getting to it but when he did WHAM. How often should i feed him? Ive heard I should vary his diet what other foods do you recommend?
