SECRETIVE WRASSES
These wrasses, none of which exceed 8 in. (20 cm) in length, are ideal for the medium to large reef aquarium. They will not harm corals, but may feed on some motile invertebrates, including ornamental crustaceans.
They usually spend most of their time slinking between live rock and among corals. They will even rest among the polyps of soft corals, although this is not typically a problem. They are usually not a threat to fishes of equal size or larger, but they might feed on small piscine tankmates that can be swallowed whole.
They are particularly shy when first added to the aquarium, but with time and if not bothered, they will become more brazen. Live food (ghost shrimps, live-bearing fishes) can be useful to initiate a feeding response. Feed them at least once a day.
Keep only one member of the genus per tank, as aggressive interactions are likely to occur between conspecifics and congeners. In the wild, they tend to be solitary. They do not bury at night.
