Appearance

The Compressed Toby is a small pufferfish with a laterally compressed body, yellowish coloration with darker reticulated markings or spots. It has a blunt face and small pectoral fins, and can inflate itself as a defense mechanism when threatened.

Diet and feeding

Feed a varied diet of small frozen foods (mysis shrimp, brine shrimp) and small pellets. Offer some vegetable matter. Live foods can encourage natural feeding behavior.

Difficulty and care for the Compressed Toby

Moderately challenging for hobbyists. Canthigaster species are hardy but can be aggressive toward tankmates and may nip at invertebrates, making them unsuitable for most reef setups. They require stable water conditions and careful tank selection.

Common health issues

Ich, bacterial infections, intestinal parasites, aggression-related injuries in crowded tanks

Origin and habitat

Indo-Pacific region from the Red Sea and East Africa through Southeast Asia to the central Pacific, including Hawaii and other reef systems.
