Microalgea (Eg. spirulina)

This species is known to jump out of open aquaria.
This species can be kept in a small tank, if it is specifically equipped to meet its needs.
It is recommended however, to keep it in an aquarium which is larger then described above.
This species thrives best when there is a sufficiently large amount of micro life (copepods, amphipods or similar) in the aquarium, so that the it can always find their own food.
This species can be bred in captivity, one can therefore consider asking your local fish store for a captive bred specimen.
These fish have small venomous teeth to keep larger fish at bay.
This is not normally dangerous for people, but it is painful when being bitten.
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.
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||Western Pacific: Bali and the Philippines east to Samoa, north to Ryukyu Islands, south to Rowley Shoals, the southern Great Barrier Reef, and New Caledonia; throughout Micronesia. Replaced by the uniformly yellow species <i>ovalauensis</i> in Fiji, and|

"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.
