Small crustaceans (Krill, mysis, artemia...)
Larger crustaceans (Shrimp, crabs...)
This species is known to jump out of open aquaria.
This species eats shrimps, crayfish, crabs, small bivalves, sea urchins, snails and similar.
This species can be extremely aggressive towards other fish.
Be careful when keeping these fish together with peaceful or docile species. Regular feeding, plenty of hiding places and a lot of space can alleviate aggressive behavior to some degree.
These fish flourish better without other members of the same species in the aquarium.
This species needs a minimum of 2 inch (5 cm) of sand in the aquarium bottom, so it can dig itself down when afraid or needing to sleep.
This species has a habit of rearranging rocks and sand.
Make sure rocks are placed securely on the substrate, so they cannot toppled over.
This species revels in swimming and requires an aquarium with ample space.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
This species can be very shy when first introduced into a new aquarium.
More aggressive fish can be introduced after this species has acclimatized.
These fish should not be kept in an aquarium where they are not allowed to rearrange whatever they can get hold of.
When younger, their pattern and shape is very different, as shown on the picture.
Fish in the genus Novaculichthys are not often seen in aquaria, but has one a big tank with ample sand, these fish are interesting to observe. When they are fully grown they will spend a lot of time rearranging loose objects.
These fish are well known for being able to swim vertically into the sand and even to swim under it.
When first introduced they are very shy and thus need a lot of calm and quiet. Later on when they have become bolder, they can become aggressive and a threat to small fish and various kinds of invertebrates.
Wrasses are nearly always seen in reef aquaria, since many of the species are both attractive and useful in battling a range of unwanted invertebrates like i.e. flatworms, pyramide snails.
These fish live of everything from zooplankton to large crustaceans, sea urchins and the like.
The needs and behaviour of Wrasses vary greatly, so it is vital to familiarize oneself with the specific species before buying one.

"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.
