Just looking for some advice on my nem. Kind of shrunk over the past 2 weeks. Have been using Wills Black box led about 24' over the tank. Settings were at 7 blues, 2 whites. I have brought it down to 5 blue, 2 white as I thought may be too much light. I've decreased feeding to 1x a week with some mysis, or reefroids. Had water checked at lfs everything is within range. Should I try antibiotics Cipro or just leave it be. Mouth is closed no contents have come out. Attached photos as well.
