Is something eating my coral?

if by chance it looks like it is melting i had this problem once i lost a lot of red mushrooms a few green ones and it affected my tree coral. Im still not sure what exactly happend but i started doing a 10% water change every 2-3 days for about 2 weeks and the corals started to come back. i was in the hospital for a week and other people was taking care of my critters so i dont know if they added someting they werent suppose to but i came home and my tank was a wreck that seemed to save it now my mushrooms are multiplying again

 

Thanks, but I think it is too late for that. They are gone.:-[ I have been doing the water changes often for the past week or so anyway, but oh well.

I'm glad you were able to save yours.
