Descriptions and further reading
Genus description (Choerodon)

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.

Family description (Labridae)

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.
