Unless you already have food cultures of phytoplankton and zooplankton established it is not very likely you can raise them. The fry go through platonic stages that need almost microscopic food and great water quality. Rodifiers are 105- 160 micrometers so are very small and a good food source till they are big enough for newly hatched brine shrimp. You will need to enrich the rodifiers with HUFA and essential fatty acids like omega 3 and 6. So you will also have to raise green water like Nannochloropsis oculata microalgae as a food source for the rodifiers. Some people have success with commercially prepared foods. Raising fry are not like freshwater and require a large amount of time and effort. If you are interested look for a book called clownfish by Joyce D. Wilkerson. Or check online for clown fish breeding.
