Galaxea all of a sudden half gone

[maymond]

So a couple of days ago my galaxea coral was perfectly fine. Came in yesterday and half of it seem to be dying or eatin by something. I had it on a glued to a rock about a week ago and never had a problem, i moved it to the sand bed. Everything else in my tank is completly fine , frogspawn, leather, zoas and clam. I do however have a from what it seems to be a stone crab that hitchiked in my tank. Ive been having the tank a year now and just saw him in there. You think he could be eating it? especially not that i moved it to the sandbed? I also saw my emrald crab messing with my leather yesterday .yall ever had a problem like that with your emrald crab? The other crab thats in my tank has blacktiped claws does that sound like a stone crab? if so i know he needs to get out

I added a Halloween hermit to my tank once and was surprised to find it eating my Galaxea. It must have been starving because it did not eat it again.

Good luck!

I'd be interested to know the tank parameters, specifically cal/alk/mag over the past week or so, sounds like a swing in something
