during their transition from endogenous to
exogenous feeding. Small prey (rotifers) are needed to
fulfil the demand of clownfish larvae in the early period
of exogenous feeding because they cannot ingest
macro zooplankters (Moina, Daphnia, and copepods;
643–728 μm) at the time of initial feeding. Rotifers
are usually mass-cultured as feed for the early stages
of marine fish larvae because of their size, nutritional
value, and behaviour5, 13, 14.
