Care

Bennett's Sharpnose Puffers require an aquarium with plenty of hiding places and room to swim. They are known to nip at corals and invertebrates, so they may not be suitable for a reef tank with sensitive species. These puffers are omnivores and should be fed a varied diet including meaty foods and algae. It's important to provide them with hard-shelled foods to help wear down their ever-growing teeth.

Reproduction

Reproduction in the home aquarium is rare for Canthigaster bennetti. In the wild, they are oviparous with females laying eggs that are then fertilized by the male. The eggs are adhesive and attach to the substrate or other surfaces.

Habitat

Bennett's Sharpnose Puffers are found in the Indo-Pacific region, from East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to New Caledonia and the Austral Islands. They inhabit coral reefs and rocky areas, typically at depths of 1 to 55 meters.
