This species is known to jump out of open aquaria.
This spicies might be a threat to smaller fishes.
This species sometimes nibbles at clams including Tridacna species.
This species will eat shrimps, crabs, small bivalves, snails and the like.
This species must be fed with an appropriately varied diet.
They can live as a pair provided they are introduced simultaneously.
This species needs good hiding places, for example, between live rocks.
This species revels in swimming and requires an aquarium with ample space.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
This species can be aggressive when kept together with fish that are very similar, or if they are not provided with adequate space.
The females are grey/brown whilst the males are green. If they are to function as a pair, the female should be introduced into the aquarium, first.
Birdwrasses (Gomphusus) are so called because of their special beak-formed jaw, which they use to hunt for prey amongst rock and corals.
They eat mainly crabs, shrimps and crayfish, but also mussels, small fish and starfish are included in their natural diet. If the prey is too large to be eaten whole, these Wrasses will hit it against rocks until the pieces are of the right size.
They normally sleep between rocks.
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.

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
