The Blue Dot Toby may also be called the Blue Dot Puffer 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.
When threatened or alarmed, it has the ability to inflate its body to almost twice its normal size. While "puffed up," its spines are held straight out from the body to discourage others from trying to eat it. Parts of its flesh are poisonous.
The diet of the Blue Dot Toby needs a varied diet of meaty foods including squid, krill, clams, and hard shelled shrimp to help wear down their ever growing teeth.
