The Orange-spotted Blenny is also known as the Redspotted Blenny or Red-spotted Rockskipper. It has a red and white body with orange to reddish spots along the side of its body.

It will do well in a 30 gallon or larger aquarium in a well-established reef system with plenty of rock work. Keep only one per tank unless you have a mated pair. It may nip at stony coral polyps or clam mantles but is not bothered by other tank mates unless predatory. It is considered a hardy fish in an aquarium if given a crop of natural microalgae to feed on.

The Orange-spotted Blenny will want to eat microalgae growing fresh within the tank. A diet providing marine and blue-green algae (Spirulina) will help the Orange-spotted Blenny thrive, along with other vegetable matter including frozen and dried foods for herbivores.
