Insufficient information

There is little available knowledge of this species, so there can be important information missing on this page.

Reef safe, when well fed

This species can be found nibbling soft coral and LPS if there is insufficient food available.

Well established aquarium with algae

These fish should be kept in a well run aquarium where they can "graze" algae from rocks and stones.

If there are insufficient algae on the rocks, it is important to feed more frequently and supplement with algae rich food e.g. Spirulina. 

Family description (Blenniidae)

There are many differences within the Toothcomb Blennies family, some eat algae whilst others eat zooplankton. There are many families of Blennies, this is merely one of them.

What they have in common are their oblong shape and long dorsal fin. Some species have small "legs" used to move around the bottom.

These Blennies do not normally get very big and are therefore a good choice for both small and large aquaria. They are not often very colorful, but many have a fun personality which many aquarists fall for.

The species of the families Aspidontus and Plagiotremus imitate Cleaner Wrasses and can therefore be difficult to identify.
