To breed? I'm not really aware of anything outside of clowns that anyone breeds, and this is only doable in a specific breeder setup. It can be pretty difficult to breed saltwater fish in general.
Certain fish will breed in captivity like dottybacks, damsels, clowns, cardinals but you’ll only ever see the eggs and getting pairs other than clowns can be hard. Raising these fish would have to be done in a separate tank and you’d need plenty of small live foods of varying sizes to feed the fry.
