· Big fish in a small pond.
Lately certain colony's of Zoa's have been closing up and melting away. Other colonies are doing totally fine. I can't find any pests and water parameters are all good. I have read of some people dosing vitamin C to help sick Zoa's. Does anyone have any experience with this or have any other ideas of where to start? They have been closing up and the stalk have been getting thinner with some of the Zoa's heads almost melting off and dying.
