Who Gives A Fish Forums

Thanks for the tips, everyone. I'll wait till mine's got more polyps and try fragging after lights-out. Appreciate the advice on the iodine dip too.

I've got a Goniopora colony that's been thriving for about six months now. It's in a 75-gallon tank with stable parameters, 78°F, salinity at 1.025, and weekly 10% water changes. Wondering when's the best time to frag it without stressing it too much.
