|Max length||11 cm (4,3")|
|Minimum volume||300 cm (79 gal)|
|Suitable for aquarium||Suitable for most aquarium|

Microalgea (Eg. spirulina)
Zooplankton (Cyclops, pods...)
Small crustaceans (Krill, mysis, artemia...)
This species is known to jump out of open aquaria.
This species sometimes nibbles at clams including Tridacna species.
These fish flourish better without other members of the same species in the aquarium.
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.
This species often has a fun and interesting personality.
This species needs good hiding places, for example, between live rocks.
Even though these fish enjoy a diverse type of frozen foods, it is imperative that its primary food, is algae based, thus ensuring that the fish`s immune system remains healthy.
This can, for example, be plant based fish flakes, Nori seaweed or similar.
Fish in the Ecsenius genus are very popular for fishtanks, normally easy to look after and fitting well in most aquaria.
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.
|Distribution||Indo-Pacific: Maldives to the Phoenix Islands, north to Ryukyu Islands, south to the southern Great Barrier Reef; throughout Micronesia.|

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
