Beware of
Jumps out of open aquaria

This species is known to jump out of open aquaria.

Can be a threat towards small crustaceans

This species can be a threat towards small crustaceans, e.g. small shrimp.

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.

Keep in mind
Requires a varied diet

This species must be fed with an appropriately varied diet.

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.

Frequent feeding

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. 

Can coexist as a pair

They can live as a pair provided they are introduced simultaneously.

Hiding places

This species needs good hiding places, for example, between live rocks.

Requires plenty of space for swimming.

This species revels in swimming and requires an aquarium with ample space.

Multiple variants

This species comes in multiple color variations which can make identification problematic.

Hermaphroditic

This species can change gender from female to male.

When a male is needed, a female changes sex and takes on the role.

Removes parasitic life

This species is able to remove parasites from fish.
It does not have a great impact on a large outbreak of marine ich (Cryptocaryon), for example, but it contributes towards keeping fish parasite free.

Constant cleaning can stress the fish in the aquarium, so one should not add this fish which removes parasites, if the fish are already weakened through other causes.

Not all specimens actively clean fish.

Descriptions and further reading
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.
