The Blue Dot Puffer may also be called the Blue Dot Toby or Blue Spotted Sharp-nosed Puffer. Members of the Canthigaster genus are called Sharp-nosed Puffers or Tobies. 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, 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 becomes alarmed when in a net, therefore, use a container to transfer it.
The diet of the Blue Dot Puffer needs a varied diet of meaty foods including; squid, krill, clams, and hard shelled shrimp to help wear down their ever growing teeth.
