 After 7 days, the fry should be ready to feed upon newly hatched Brine Shrimp.The fry appear to be almost transparent at first, with the exception of the eyes, and do not begin to develop the 'lozenge' shape of the adult body until the differentiation of the finfold into the unpaired fins is complete (around 4–6 weeks).Once this process is complete, the fishes are ready to take sifted "Daphnia".
