This will help it adjust to the new diet. Feed it once a day. Determine the amount of food it consumes every time food is brought to it.

Try to avoid stuffing too much food into the tank if there is no cleaner fish to clear away remnants. Most fish develop ich as a result of wasted food staying longer inside the tank. If possible, adopt a cleaner fish that will clear away any leftovers. Keep a close look at the fish. If there are signs of depreciating body size, try to keenly observe the diet.

While feeding, be careful with the tank lid as they are known to jump quite highly. If not properly fed, the fish claws at corals and may nip clams.
