You could do nothing. It takes lot of research and care to raise clowns. Need to get eggs out night before hatch. They hatch in 8 days. You need live rotifers from birth then older fry will eat baby brine. Phytoplankton will feed the rotifers. I have a spawning pair and waited months before I started to get rdy for raising them. Of course soon as I am setup and culturing phyto and rotifers the clowns havnt spawned in months. So I have the know how but now my clowns havnt spawned in few months.
