This study investigated the artificial propagation of Sexy Anemone Shrimp (Thor amboinensis). The relationship between carapace length and the number of larvae was investigated, as were the effects of different types of diets, feeding concentrations, feeding opportune time and temperatures on growth and survival. The relationship between the number of hatched larvae (Nlarvae) and carapace length (CL) was expressed by the following regression equation: Nlarvae = 0.47 × CL5.0328. Larvae fed with the nauplius of Artemia salina at 0.5-2/ml had better survival and growth rates at 10 dph (days post-hatch). Survival and growth rates were decreased when the larvae were not fed instantly after being hatched. Better survival and growth rates were obtained at 27 and 30℃. Some larvae had developed into postlarvae by 24 dph, but most of the larvae developed into postlarvae from 26-45 dph.
