The Rippled Rockskipper Blenny (Istiblennius edentulous) is also known as the Coral or Rippled Blenny. They have a long dark body with occasional stripes; some specimens may also have white or brown coloration. As their name suggests, they can be found in rocky reefs among the Coral Sea of Australia. They are able to breathe air, similar to mudskippers, and if trapped, can hop from tide pools into the ocean. They graze on algae throughout the day and require an herbivorous blend of food. They reach a maximum size of 6 inches and should have plenty of live rock to hide among or perch upon. They can be territorial of their sections of the tank, so other fish should be introduced before the blenny is too established.
