How to get rid of Emerald crab

[jeemann99]

I purchased an emerald crab to help with bubble algae is gone, but now he is taking a liking to my corals. I tried everything including traps and no luck. I have to many rocks and corals to start tearing it apart.

What fish can I get that will eat this thing?

Has to be reefsafe

What always works for me, kind of the same concept/idea as the others stated,
•take a water bottle
•cut the top 1/4 of the bottle off
•invert the 1/4 narrow top in the bottle
And there you go, place it in the sand and throw something tasty for them to eat and it's very difficult for them to get out. I found out this is decent way to catch bristle worms that get fairly large in.
Good luck

If not try tweezers or something to skewer him if it gets to that point

I've used a tall glass leaned up on a rock with a piece of food in it. As for fish, maybe a trigger? I'd ask the fish section.

Trigger probably isn't reef safe.

I've taken to skewering them or crushing them between the rocks. Crude but effective.

Ive good a trigger in my tank. Whats reef safe? He sures hell doesnt pick at corals. But loves clean up crews.
So i clean glass manually and run gfo.

I managed to get 1in large snails that he doeant really bother.
And they learn to come out at night when the trigger sleeps

I think triggers typically are known for eating shrimps, crabs, and snails. I've had blue throats, haven't seen them eat corals or anemones. But I've seen them rearrange rocks and corals, not eat them though.

Ive gotta 6 inch niger in my tank and he doesnt touch the corals,he does eat crabs and shrimp though. I do have some snails in the tank so he takes it easy on them.
