In my 16 gallon, i have some sps growing, i have had this particular acro for about 6 months or more and it has been doing great, growing new branches. Although a few days ago my birds nest that i just got fell onto my acro. I was out from the house for a while and when i came back, my acropora’s ends that got touched by the other coral was white (dead) the rest of the coral is healthy though, and i have re glued the other coral. Should i just leave it be? Or should i do something to the dead parts
