So I've got a pair of clowns and they regularly lay eggs. In the past I haven't really had much of an interest in trying to get the fry to hatch, but this time they laid the eggs on the inside surface of a clam shell (the clam died so the shell is obviously empty). If I remove the clam shell and put it in a separate tank, what are my odds of getting baby clowns and what should I do to increase the odds of the fry surviving?
