Worth a try and very rewarding!
On the hole happy clowns will breed in TIME... time being the factor.
it is very easy to do on the cheap, you dont need a fancy system set up. A small tank with a couple of airstones in will seee you good. If the breeding bug bites it can be a dear do, be warned!
The time you will have to dedicate to raising larvae is something you will have to consider, i find this this the biggest hurdle.
The thing is to let the clowns settle and keep them happy. While this is happening you will have plenty of time to research and practice raising food cultures.
As above Joyces book is a good choice, and a great read if you arnt breeding so worth the expense.
