Breathing of Arothron manilensis

The narrow lined puffer is a beautiful saltwater puffer. They will do well in a tank with live rock and enjoy searching the rock for living things to snack on. They are mild toward other fish, but are not reef safe as they will readily snack on many invertebrates found in a reef. They do tend to be more territorial and will not accept conspecifics.
