The research container used was a transparent fiberglass tank capacity 30 L as many 8 tanks. juveniles were 4 individuals /tank an average size between 55-68 mm. Each equipped plastic bottle filled coral fragments white sand water filter for recirculation. Water changes carried out every 2 days much 16 %. treatment given salinity: A. 25±2 ppt, B. 30±2 C. 34±2 ppt (sea water), D. 40±2 ppt. Acclimatization against 3 days. design completely randomized treatments replications. results showed that could 40 has significant effect on rate, even lowest is found 25 seen be experiencing health problems.
