I've a 5 month old set up, all the parameters are perfect. Every week without fail I do about a 15% water change. I added a meat pink meat coral about four months ago. It has continually gotten bigger and full up until this morning. I noticed it didn't swell to it's normal size, only about half as much and the color looks a bit off and throughout the day it continue to shrink down in size. I've got LPS, SPS & Softies in the tank and they're all doing fine. I'm concerned I might be loosing it and haven't a clue why. Can anybody give me a suggestion as to what might be going on?
