The Saddled Toby is also known as the Black Saddle Pufferfish, Blacksaddled Toby, Valentini Toby, or Saddle Valentini Puffer. Members of the Canthigaster genus are called Sharp-nosed Puffers or Tobies. The Saddled Toby is a bright and colorful fish with dark brown bands across the midsection, brownish-orange spotting on the lower half, yellow fins, and blue striping running along the back. It lacks pelvic fins, but has learned to use the pectoral fins to move about the aquarium.

A 30 gallon or larger, fish-only aquarium is suitable. It will fight with conspecifics such as the filefish, large finned fish, and other tobies. It may be aggressive at times, nipping the fins of tank mates, leaving a circular hole as its mark. It will also eat invertebrates found in a reef tank. Its teeth are actually a fused beak-like structure.

Parts of its flesh are poisonous. 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 Saddled Toby needs a varied diet of meaty foods including squid, krill, clams, and hard shelled shrimp to help wear down their ever growing teeth.
