I bought zoanthids from the petstore, and they were doing okay but suddenly stopped. All my aquarium levels are normal, with nitrite running slightly high. I just turned on the current this morning to help, but my zoanthids won’t open all the way, and they’re growing algae, what should I do to help
Take a very soft tooth brush and brush off the algae. Then move them to a shelf or rock an inch or two off the substrate. Third and final get some green phytoplankton and feed them when they open.
