This three-inch Sharp-nose puffer (Canthigaster cinctus) appears to be taking a rest on a sponge, a common behavior among these petite fish. The clasped, often curled position of the caudal fin is normal, even when swimming. Sharp-nosed puffers are also capable of inflating themselves. Their small size (maximum about five inches) suggests they may use a much wider variety of hiding places on the reef-- I can certainly attest they are more difficult to corner for a photograph. This is one of several different coloration patterns among the numerous species of sharp-nosed puffers, with three triangular pigment "saddles" across its back ("cinctus" in the taxonomic name means "band").
