Nocturnal

This species is nocturnal and therefore the most active when the light is dimmed or turned off.

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.
