Genus description (Hologymnosus)
Hologymnosus species are very active and relatively large, they therefore need a lot of space. Has one space enough, these fish are well suited to aquarium life.
They cannot crush prey like many other Wrasses, but eat a range of invertebrates and fish, as long as they can be swallowed whole. Occasionally they can be observed smashing up their prey on rocks, into smaller pieces.
They dig themselves into the sand when feeling threatened or needing to sleep. When they are transported without sand in the container, they can sustain injury around the mouth. When selecting fish in the shop, this must be checked for.
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.
