Descriptions and further reading
Genus description (Cheilinus)

Fish in the genus Cheilinus are larger than most Wrasses, even up to 6.5 foot (2 metres).

These fish are a threat to most invertebrates -but not corals- and small fish. It is probably necessary to feed with living foods at first and after some time with large pieces of seafood every, or every other day.

It must be noted that even though they can be aggressive themselves when first introduced. They can easily be stressed by other fish, or indeed aquarists, before they are properly acclimatized.

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.
