Good job on the breeding, you sound like you had a good first shot, and the tank looks great.
I too would advise you to buy a small sponge filter (should be cheap) to use in the fry tank. This should give you cleaner water, and faster healthier growth rates. Of course this needs to be done along side water changes (big and often) but I think the filter will help.
All the best raising the fry to full size.
