I've heard of commercial breeding being done with the use of hormone injections. I actually read a rather detailed article about it over at the puffer forum a year or two back. I've heard of accidental breedings in home aquaria but none have been well documented (or at least that I can find). I would love to breed these guys and will attempt it after the move if I can get a good school going and grow them big enough ( I have three new youngsters ranging from 1.5 to 3 inches right now, had three before that all died of a very bad ich infestation that were all over 5 inches). I've seen large clowns before and not all of them get pale. There are 4 large ones at a LFS near me that are almost black in color, and I've seen larger ones that still show their bright juvie coloration. I think alot depends on the fish, environment, and food, which is why I've seen so much variation in coloration as they get older.
