A well-established 30 gallon or larger aquarium with multiple swimming levels and plenty of rock is a suitable environment. The Segmented Blenny is not usually aggressive unless the tank mates appear to have a similar shape as it does. It is best to house singly unless kept in a larger tank and the two are a mated pair. It tends to perch and hop from rock to rock looking for microalgae to graze on.

The Segmented Blenny is a perfect candidate for the reef aquarium and is considered reef safe but may nip at the polyps or bases of Acropora sp. and other SPS corals. If the SPS dominated aquarium is not heavily stocked with mature colonies these fish may damage Acropora sp. and Montipora sp. in these displays.

The Segmented Sailfin Blenny does best in well-established aquariums with large amounts of natural algae to feed on. The diet can be supplemented with vegetable matter, Spirulina, and herbivore preparations.
