Descriptions and further reading
Genus description (Pseudocheilinus)

Fish of the Psuedocheilinus are popular aqauarium fishes, as they are attractive and effective at keeping flatworm and pyramid snails at bay.

It is the Psuedeocheilinus hexataenia (Sixline Wrasse) one sees most in the trade. P. hexataenia can occasionally show extreme aggression towards other fish of the same size, in which case consider fish of the Halichoeres genus instead.
Eventhough these fish can be very aggressive, if they are hunted by larger, even more aggressive species, they will hide themselves.

They don´t dig themselves into the sand, but sleep between the rocks.

It is normally easy to feed them with different types of frost and flake foods. Some individuals like to eat small crustaceans, but this is usually not a problem.

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.
