Help me! Colt not looking good

[chbarber]

I have had a Colt for about 2 months now. I started fragging it about 3 weeks after I had it and about a week or two ago it started shrinking. It was probably 9 inches tall and now it has shrunk to maybe 4 inches. The bottom turned almost white because it got between two rocks and I think they may have crushed it. Is there any hope for this coral? Nit/Ammon=0 Calcium=440
