their easy but only in small numbers, best way is to but the eggs as their cheep and hatch them, 1 gramm of eggs contails something like 240,000 eggs!!!!!!
As for breeding keep them in a well light tub or tank with a good salt mix and they will breed on theor own, however only a coule will sruive as the need to be feed lots of phytoplankton's to feed on, but the get to full size in 10-15 days.
