ThRoewer, if I was going to breed clowns I would have the same approach that you do. The Percula pair that I have I'm sure were from the same hatch, but I don't have any ambitions of trying to raise the fry. My pair are as perfectly matched as I've ever seen which looks great. I'm however getting disgusted with them not being hosted by any one of my 4 BTA's.
So I'm thinking about either trading them in for a different pair or trying to find a small gig. I do have reservations about getting a gig. I'm worried it would eat other fish in the tank, and then have to worry about how big it will get in my 40b. Maybe get a small one 6" or so and not directly feed it or if I do not very often so it doesn't grow too quickly.
Do you have any thoughts or suggestions on this?
