I worried about this scenario since my clowns are flirting with each other. I did some reading on
Wetwebmedia, Aquarium, Pond, Marine and Freshwater Fish, reef tanks, and Aquatics Information and other sites. If you really want to be a clown breeder, get a second job. WWM suggests letting the first batch of fry go because it is a math game. Fry hatch at night and it is best to collect them then, by the next day you probably will not see them. Your clowns will spawn again. Keep count of how many days it takes for the eggs to hatch and then siphon the fry out. Be prepared for the feedings though. They cannot eat like your other fish until they get bigger. You will need to look into rotifers, baby brine yadda yadda yadda. I read some guy's log online about what was fed, how many batches of fish he lost and how many actually survived...1 fish out of a few batches and sold to the LFS for a $15 store credit. Seems like a blast until you figure in just how much money was spent to keep that one fish alive for 6 months.
