I started just like you watching the first two hatches and then deciding to try to to help them survive. If you don't have the time it's best to let them be, however, if you decide to make the time to raise the fry make sure you do it for the experience and learning. You can be successful with leaving the eggs right where they are, I just kill the pumps on the night of the hatch and use a fry trap. For my first try at it I was plenty successful just using a flashlight and a siphon hose to catch the fry. You won't catch all of them, but it's not necessary you'll still have plenty of fry to work with. I prefer this way as the clowns do a great job of caring for them and I think it's more natural for them. If raising for maximum numbers of fry, then you would want to try a clay pot and remove the fry the night before the hatch. You can check out my thread and I'll be happy to help if you decide to go forward with raising them, it is rewarding and I found it difficult to part with my babies even though I knew 27 clowns in one tank was a really bad idea.
When I bought out another tank and got a pair of mated clowns with it earlier this year, I didn't know what to expect. I briefly tried to sell these before the family got too attached, which took only about two days before they were off the market. These are in my frag tank since I already have...

Some things have gotten easier, like I have been told Atlanta Aquarium is carrying rotifers and Reef Nutrition products, that alone will save you about $150 I spent in shipping costs. My most successful batch was actually the first one, there were several batches for me where only 1-5 fry made it to the grow out phase. The tricky transitions are from feeding rotifiers to either pellets (TDO A) or live brine shrimp as an intermediate food before pellets, the first water change, (drip in everything, make up water, RODI replenishment water) and lastly moving them out of the fry tank into a grow out tank.
