Experiment is used Feber  tank with 1m³ size as much as 12 tanks.  Animals used were seeds of coral trout grouper with initial body length on average 3 cm with each treatment density of 100 fish / m³.  Coral trout grouper seed kept in tanks Feber. The type of feed given in the form of a commercial pellet  feed with protein content of 48%, and additional food such as shrimp Mysid (jembret) for 10 days. The frequency of feeding 3 times a day. Feeding treatments tested were (A) = 5%, (B) = 10% (C) = 15%, and (D) = 20%. Research using completely randomized design with 4 treatments, each treatment was repeated 3 times. Data were analyzed using ANOVA and descriptive. The results showed that survival was significantly different (P <0.05). The highest survival is feeding treatment  (C) = 15%.
