Coral being eaten?

[ReefPrincess007]

I’ve had this tank for 4 years with very few problems and I’ve never seen this before anywhere. This particular coral has been in the tank since day 1.
36 G reef tank one clown fish. Water is in good balance. A few notes:
1) found a good sized hitchhiker crab 2) could hurricane power outage stress (3 days) be showing now? I had bubblers and ran filters on the generator for 6 hours per day.
Suggestions on what would cause this. Thank you!

Water parameters are all good? Ca and Alk ? How fast did this happen was it overnight? I have never seen this before either

 

[ReefPrincess007]

Yes. Parameters are all fine. Maybe not overnight but within a day or 2. Crazy?!

The hitchhiker crab would have me concerned. I've never seen that before. #reefsquad?

When in doubt, get it out That look like major eating on the stems. Do you have a picture of the crab?

Looks like my fungia after one "dinner date" with a gorilla crab.

Most likely gonna have to frag that coral at the part of the base where it's been chewed. Try to get the crab out and get a pic for an ID

 

[Lovemyreef2015]

If you can i would remove the coral and put it in a bucket before you try to remove the crab so it can't Escape in the tank.

Thank you all. Crab is out, coral fragged. We’ll see how it goes!

That doesn’t look reef safe to me at all

I have a gorilla crab and an emerald crab that live in my sump. The gorilla was a hitchhiker I found and the emerald went rouge and chewed on my frog spawn. The fleshy part not the skeleton I did not think crabs ate calcium carbonate. Good that you got it out. that thing looks nasty.

Who knows if that’s what it is? I’ll sacrifice a nasty crab to see. Lol. Hope this fixes it.
