Sorry I missed this thread johncomeau8.
My zoanthid's get plenty of light. Thats all the feeding I give them. I'm sure when I feed baby brine shrimp to my sun coral and popcorns some flow over to the zoa's but I do not target feed them.
If they are open while the light is on they are getting what they need. If they start to stretch towards the light during the day you may want to move them higher in the tank.
Warning; Bulldog Pleco guarding my Sons tank now..
Please remember; every keystroke has a consequence.
