Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 25 - 28; Anale stekels: 0; Anale zachte stralen: 22 - 25. Ranges from pale greenish to dirty white in color; blackish-brown saddles above; normally with a round dark blotch above origin of anal fin; soft dorsal and anal fins hyaline, tips dusky; caudal fin yellowish (Ref. 4421).
Inhabit clear lagoon and seaward reefs to at least 25 meters (Ref. 5503). Solitary or in small groups (Ref. 9710). Adults usually in pairs, but sometimes seen in small aggregations (Ref. 48637). Mimic the poisonous puffer, Canthigaster valentini which it greatly resembles. Feed on eggs, gastropods and grazes the substrate (Ref. 5503, 48637).
