Last night I came home too see my open brain has started to bleach a little. The part you see in the picture was actually up against the live rock, when the brain would PUFF up this part would be rubbing against the rock.
Could this be the cause of tissue damage? Will this kill the whole coral if not can it heal?
Half of the skeleton is showing now and it no longer blows up at all. I did a 25% water change and bought a 24" 4xT5 HO light even though I'm not sure of keeping my 25gallon once my 180 is fully up and running.
