Have you bought Wilkerson's book? The hardest part of raising fry is the first week. You pull them through that and you have it made (well as made as a breeder can...). It sounds like you are either getting mechanical damage of the fry in the growout tank or they are not eating. What do you see them doing? How are they reacting to light? You want them to sit in the middle of the water column only using energy to dart 1/2 a body length for rotifers. I too suggest live phyto use in growout. It keeps the water cleaner, feeds the rots, and has the added advantage of diffusing the light. Best advice though is to read Wilkerson's Clownfishes and read the old threads on breeding clownfish. If you need to narrow the search look for my name, JHardman, Ediaz, or any of the "old timers".
