Overstocking my 30 gallon saltwater tank??

you could probably put either of the two or both since they are small and dont put off much waste however, id take out the domino damsel. it may cute now but not when its six inches ugly, and terrorizing all your fish. taking him out would lessen the bioload even more. if you do decide to take him out and you dont want to move all the rock, i have a friend who caught a damsel with a tiny fishing hook!
