If you're thinking of breeding to make money, I wouldn't bother honestly. (With any clownfish). From all that I've read, seen, heard, etc... And ive done a lot of research on breeding clowns, as a side project (for fun, not to make money). Unless you hit the "what's hot right now" fad you won't make a lot of money.
If you're asking whether or not you will be able to sell the fish at all, then yes, I would think so. As long as the fish are healthy and the local market supports it. If you were thinking of breeding tomatoes, maroons, etc, you might want to pick another type though.
Black and white clowns usually sell for more $ than standard orange and white clowns in stores. I'm always in favor of people raising fish, corals, anemones, etc as much as possible so we're not yanking them from the ocean. Captive breeding with almost any fish species is a step in the right direction.
