As aquarium fish
Jumps out of open aquaria

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.
This species likes to eat tubeworms.
Can be a threat to small fish

An effective invertebrate hunter
These fish will hunt crustaceans, sea urchins and worms in an aquarium, very effectively.
Demand a very large aquarium when fully grown
This species needs a very large aquarium when fully grown.
Exactly how big the aquarium should be is hard to say, but the size of this species is such, that it cannot normally be kept in a home aquarium.
Rearranges rocks etc.
This species like to move rocks and sometimes corals in the search for food.
Sensitive during transportation
This species is very sensitive during transportation and acclimatizing into the aquarium.
Deep sandy substrate
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.
Requires plenty of space for swimming.
This species revels in swimming and requires an aquarium with ample space.

Genus description (Halichoeres)
Fish of the genus Halichoeres are very populair in aquaria, as they are attractive and effective at eradicating flatworms and pyramid snails.
They are generally more peaceful than Pseudocheilinus hexataenia, which are often acquired to the same end. However, most fish of the Halichoeres genus will quickly become too large for smaller aquaria.
There is a difference in which food these fish live on, some on small invertebrates, whilst others can crush various crustaceans. Some species will take prey larger then themselves and smash it against rocks, so be aware of this when one has small fish, crabs, shrimps, snails etc. in the aquarium.
These Wrasses will dig themselves into the sand when feeling threatened or needing to sleep.
When they are choosen at the fish store one must make sure they are not injured during transport, especially in the area around the mouth. If the fish will be long in transit, it is a good idea to have enough sand in the container used so they can bury themselves.
They have an excellent biological clock, but after transportation it takes a bit of time before it start working properly again.
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.
