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.

Aidablennius (Sphinx blenny)

Aspidontus (Sabretooth blennies)

Some species in this genus imitates cleaner wrasses.

Blenniella

Blennius

Cirripectes

Ecsenius

Fish in the Ecsenius genus are very popular for fishtanks, normally easy to look after and fitting well in most aquaria.

Exallias

Hypsoblennius

Istiblennius

Meiacanthus (Sabretooth blennies)

Fish in the genus Meiacanthus have small venomous teeth, used to defend against larger fish, which in turn will avoid them in an aquarium.

This kind of Blenny is ideal for small tanks, as long as there are plenty of living rocks and hiding places. It is relatively hardy, easy to keep and peaceful towards other fish.

Omobranchus

Parablennius

Plagiotremus (Sabretooth blennies)

Some species in this genus imitates cleaner wrasses.

Salaria

Salarias

Fish in the genus Salarias are often used to combat algae growth, especially the Jewelled Blenny is popular and is seen in many aquaria. There is little difference in what these fish eat, but they often remove the filamentous algal layer and detritus from glass and rock. Some individuals eat also other kinds of algae, like i.e. green hair algae.

Be aware that they can be very aggressive towards other Blennies. Also in some instances towards food competitors, like the Surgeonfish, Rabbitfish or similar.

Scartella
