The Smith's Blenny is also referred to as White's Blenny, White Blenny, Smith's Fang Blenny or Disco Blenny. Its body is mostly blue with a black stripe, which starts at the chin and runs through the eyes and down the dorsal fin.
It tends to do well in an aquarium if provided with live rock in a 30-gallon or larger aquarium. The live rock provides places to hunt and feed on small crustaceans as well as places to hide. It is not usually aggressive unless the tank mates appear to have a similar shape as it does. Its fangs are more of a defense mechanism used for biting an aggressive fish back.
The Smith's Blenny should be fed a well balance diet of carnivorous foods along with a selection of foods designed for herbivores. These fish should be offered small quantities of food several times per day.
