This study describes the growth of juvenile clownfish, Amphiprion percula Lacépède 1802, fed with an artificial diet at six ration sizes of 2, 4, 6, 8, 10 and 12% of body mass per day (BM day−1) each at a feeding frequency of once, twice and three times per day. The effect of ration size on growth depended on the feeding frequency. In fish fed once a day growth did not improve above a ration size of 8% BM day−1. At two feedings per day fish required a ration size of at least 6% BM day−1 to achieve good growth, and fish fed three times per day grew at similar rates above a ration size of 4% BM day−1. A model to estimate the combined effect of ration size and feeding frequency is presented. The results lead to the suggestion of a simple length-based feeding regimen that could be tested in future studies on this species or adapted for use in other species.
