That really sucks to see. Sorry to see this.
I had a gig rip it's foot (ok, I ripped it) when I tried moving it, maybe 5 years ago. It was attached to 2 rocks, I tried moving only one and didnt' realize until too late. Here are some pics.
This guy
Turned into this
When I tried to move it, this happened.
Took a month to turn into this after the rip happened.
I thought I was in the clear. It completely healed. Dismantled my fuge and one of two 75's tied to the system. Everyone crashed. Lost most everything overnight. I was trying to upgrade, (did), but needed to do some home remodeling before, and the tanks needed to move in order to remodel. I had this guy around 9 months before I decided it needed a bigger tank, and lost it in the crash.
Reason of me telling you, is, (trying to give you some hope) as bad as yours looks, if you provide it with the best care possible, IMO, it can recover.... But, that's pretty bad looking. Don't count that guy gone just yet. 100% water changes in the beginning can reallly help a lot. Best of luck, keep us updated as it progresses.
