A few days ago I noticed that when the lights are off there are a bunch of white dots on my red planet acro pictures attached). They move very slowly and disappear within about a half hour of the light coming on. The coral is starting to show some stress such as pale flesh and a white spot at the base. I added a bunch of corals about 2 months ago but dipped them all and haven't added anything since. I can't seem to find anything online that fits the description of what these things are. AEFW (but they're white)? Any help is appreciated.
