This is my favorite part of my tank. He began about two years ago the size of a quarter. Moved him to the 300 gallon 10 months ago and he split like four times. I normally feed them once week as long as they arent on walkabout and being silly. If they are in the their normal spot the get fed. Beautiful fellows. Clown fish wont go near them though. They are in love with a magnet cleaner.
