raising fry is not an easy task, but its definately do-able.. I wouldnt bother trying to do much with this batch, but you can start getting prepared for the next. There will be _many_ more to follow..
If you want to get serious abbout reaisng some fry, then the first thing I recommend is getting the book "clownfishies" by Joyce Wilkerson. and I also recommend hanging over at the clownfish/anemone forum, and maybe the fish breeding forum.
You are going to need to get some rotifer cultures going. Rotifers are easy. Growing their food (phytoplankton) is not so easy. Many people use many different things to feed the rotifers from yeast diets, to frozen algae paste from reed mariculture. I use DTs and am very confident that it is the best way. (not the cheapest but definately the best). It will take a few weeks to get the rotifers going well enough to keep the fry alive. Once they are doing well, you will harvest about 1/2 everyday, and re-feed them again everyday. They multiply very quickly.
After this batch hatches, I would try to slip a white ceramic tile into the place where they last spawned. Some have said that this will disrupt the spawning cycle and indeed it could. IME it has not .
Hopefully they will spawn their next batch on the tile, so that it can easily be removed when they are about to hatch. Some prefer to let the clowns spawn on the rocks, and then collect the fry after they hatch. More info on that in Wilkersons book.
You will need to get a 5 gallon tank, a heater, an air pump, and a 4" bubble wand.
If they spawn on the tile, you will remove the tile on the evening that they are going to hatch, and put it into the 5 gallon tank, leaving the parents in their existing tank. The fri will hatch that night..
Whenyou get this far, let me know, and I can tryto help further.
Good luck
