Rainbow Wrasse   (Thalassoma amblycephalum)
Family: Labridae (Hogfish, Wrasses)
Natural Range: Indian Ocean, Western Pacific Ocean
Depth: 3 to 50 ft.   Size: 5.5 in.   Jumps: Yes   Space: 75+ gal.
Reef Safe: Yes   Care Level: Easy   Temperament: Caution
Diet: planktonic crustaceans - copepods, shrimp and crab larvae, etc.
Natural History: The Pacific Rainbow Wrasse is found on lagoons, patch reefs, and outer reef faces in large feeding groups, often in high current areas. Juveniles are rather drab in coloration, with blue side, white belly and fringe colors on the dorsal and anal fins. The terminal phase males have a green head, yellow thorax, and a broken-orange abdomen. Juveniles and adults are reported to participate in cleaning behavior.
Husbandry: The Rainbow Wrasse is smaller than many of its Thalassoma relatives and poses less risk to ornamental shrimp in captivity. It is considered a very hardy aquarium species. Terminal phase males should not be kept with other Rainbow wrasses unless the tank is very large. This species is reported to be a very good jumper.
Reproduction: Large groups participate in spawning behavior by swimming up into the water column and then down, releasing gametes on the descent.

AKA: Blunthead Wrasse, Pacific Bluehead Wrasse
