Scary thing in Tank

[Barb Hillson]

Just saw this scary thing in my tank and not sure what it is or if it is good or bad. Can anyone help me identify it.

Gorilla crab? How many legs does it have?

 

[Barb Hillson]

Not sure could only see 3 or 4.

 

[Barb Hillson]

Is it something to worry about. Never bought it so must have come in the live rock.

When in doubt, remove it. Could also be those spiders one of the guys on R2R had a long battle with. I'd pull it for closer inspection.

Get it the heck out...looks like a zoanthid eating spider to me.

 

[Lionfish Lair]

I don't think it's a sea spider, as I can see lots of little hair like projections on the legs.... like a crab.

 

[Untamedrose]

ok might be side view gorilla. Either way needs to get out get better photos of it

 

[Lionfish Lair]

Oh, I think it's still safe to say "get it out and see what it is".... just don't tear apart your tank to do it.

+. Try and catch to put in your sump or give to someone that is into crabs

Looks like a gorilla crab. 90% sure. But 100% sure it is a drab of some sort. Pull it.

Its definitely a crab - no good hitchhiker crabs (besides acro crabs, I guess).

 

[CodyRVA]

When in doubt, yank it out.

It looks like a gorilla crab. I would remove it as soon as possible.

The first question would be, has there been any negative effects in the tank? Such as things going missing or corals looking bad? Put some piece of shrimp by that area to get it to come out for a good pic..
