The Crowned Toby, is also known as the Crowned Puffer, Four Bar Pufferfish, and commercially as the Hawaiian Saddle Puffer. Members of the Canthigaster genus are called Sharp-nosed Puffers or Tobies. The Crowned Toby is light blue ventrally, and the darker dorsal portion is divided by light blue stripes. It lacks pelvic fins but has learned to use the pectoral fins to move about the aquarium.

A 50 gallon or larger, fish-only aquarium is suitable. It may be aggressive at times, nipping the fins of tank mates and leaving a circular hole as its mark. Its teeth are actually a fused beak-like structure. It will eat invertebrates found in a reef tank.

It has the ability, when threatened or alarmed, to inflate its body to almost twice its normal size. It becomes alarmed when netted, therefore, use a container to transfer it.

The Crowned Toby needs a varied diet of meaty foods including squid, krill, clams, and hard shelled shrimp to help wear down their ever growing teeth.
