I have looked up past questions about this but I got a quick one here. My new coral bueaty has been in the tank for a week now it is eating but stays in the rocks all the time do they not come out much or what is going on added yellow tang and CB at the same time only had two clowns in before these two.Tang is loving life clowns are as well CB just stays in same two spots both under over hangs of rocks or in cave. Is there something I can do or it is what it is strange.
