Two weeks ago, i got a shipment of coral from liveaquaria, the monti has been showing some stn, starting on the left and slowly moving right, no polyp extension. I had it on the bottom for a week and then moved it slightly higher. I have it in the same flow as my other monti and birdsnest. Not really sure how else i can help it, or even whats causing the tissue loss. Im thining maybe the lights, since i use t5
