i have gotten aptasia in my tank, and have been trying to treat them with stop aptasia. about a month ago i noticed some aptasia in a cluster of polyps. i treated the aprasia with an apllicator directly into the body of the animal, but every since the polylps wont open. some of them will open slightly but most will not. they don't seem to be dying but will not open. nothing in the tank has changed and all of the tests read fine. any thoughts?
