Small crustaceans (Krill, mysis, artemia...)
Larger crustaceans (Shrimp, crabs...)
This species eats shrimps, crayfish, crabs, small bivalves, sea urchins, snails and similar.
These fish flourish better without other members of the same species in the aquarium.
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 fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
This species needs good hiding places, for example, between live rocks.
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 aggressive when kept together with fish that are very similar, or if they are not provided with adequate space.
This species can be very shy when first introduced into a new aquarium.
More aggressive fish can be introduced after this species has acclimatized.
Species in the genus Choerodon become quite large and require plenty of space, as they are very active and intelligent fish. Large individuals are known to spit water upwards from the tank, so site electrical instalations with care.
They can be fed with various kinds of seafood, frozen and dried foods. They should be given food several of times a day, as they are active fish.
They can be aggressive, but if one avoids introducing docile fish, or similar Wrasses afterwards, it should be fine. Large specimens will eat various crustaceans, snails, starfish and sea urchins if they are within reach. They will also move lose corals and stone about in their search for food.
Choerodon fasciatus are less likely to eat invertebrates and move stones and corals then the other species, they can -with care- be kept in a reef aquarium.
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.
