Emerald crab nipping at torch?

Medmondsii · Jul 31, 2022

Do emerald crab nip at torches are night? I took some pictures. I thought they were reef safe? Anybody have this issue before?

Might be going for algae around the base? I would think the torch would be retracted if the crab was trying to eat it.

Do you feed the crab?

I had one that cleaned my gonipora every night. Never bothered it.

Goniopora and an Emerald Crab?

I couldn't catch him if I had to, but is he eating my Goni? He gets on it in the middle of the night and cleans it I guess. They have both been in the tank for 9-10 months. I've seen him clean my green one before and didn't really pay attention to it. Both green and red Goni are flourishing...

Chances are just cleaning around it. Crabs are opportunistic feeders though but I still doubt it's going for the torch. As mentioned above it would have retracted.

I came home from vacation to fins my emerald eating what was left of my new duncan.
I cant know if it was the emerald that started it or the peppermint. Both got sumped

emerald crabs are know to eat LPS corals, so dont be surprised if you see it gone one day. I had a halloween crab eating on my sps, I was lucky the are easy to remove... I have emerals crabs in my sps tank, and they dont do any harm to sps, they like fleshy soft food...
