View Full Version : Hitchiker crab Id please

10/06/2017, 09:58 AM
Been reading about Gorilla type crabs or non safe reef hitchiker crabs. Found this little guy in my Montipora and there was some bleaching around the area where he was hiding. Am I to assume he's been eating the coral?

I caught him and here he is? Is this one i don't want?

Looks like a Teddy Bear Crab. If it is, it's generally considered to not be reef safe.

I toss guys like that into my Frag Tank's sump where there is a ton of live rock and not much else. They're happy?, I'm happy, and the corals are not bothered any longer

Thanks for the responses. I heard most "hairy" crabs are not good and better safe than sorry plus i'm pretty sure the bleached part of the montipora is where is has been feasting. I have a backpack fuge in the back of my nano i guess is where i could throw him but i head if these crabs are specific type of eaters (e.g coral eating) without this particular food it will perish anyway.

I threw my undesirable hitchhiker crabs in the aggressive FOWLR tank we had at work.

This might be too gruesome, but does anyone kill them like by freezing and them use them for food for the tank? Seems better than just letting them die.

I found a crab just like that in my mixed reef. Ate sps polyps and a couple small clowns. Never found out the name.

I had a similar crab back when I had ny 300g.

Didn't bother a thing and I fed it during feeding time. I actually thought it was one of the coolest inhabitants in my tank!

Here's my experience with mine, have some big pics of it in this thread and got some of the old pics working again so you can compare to your crab ( this was back in 06):

Keep your crab and see how he does. Most peeps that saw my tank thought it was cooler than all my fish lol! I HOPE to get a crab like that again when I order my lr for my current setup!

He never bothered coral or fish. Maybe keeping him well fed was the rrick, maybe I just got lucky.

Man,yours is way hairy. Mine is not as much and to reply to mikenh77, not sure how large your crab was to eat small clowns but mine is one quarter the size of a dime.

He is in the fuge now.
