in my 32 gal tank ive now found 3 types of hitch hiker crabs

the first is a rather large rock crab... i dont think they are too worrisome but when they get bigger are they are worry?

the second is a little tanned one thats really hair.. hes mayeb a half an inch at the moment... will he be a problem?

the last one worries me some... hes black and not hairy...

he might be gettin up to 2 inches across (including legs)... and has big fat claws.. one seems ot be bigger then the other but each exceed or equal around half an inch.. i think he might have been the bane of my little yellow clown goby?

anyone knwo if any of these are a problem and how to catch them? they are all speedy as the devil
 
I had one of the Rock Crabs and it ate good by eating my Peppermint shrimp. It took me dipping my LR in a Freshwater dip then shaking him out of the rock. It took about 30 minutes of shaking the rock to get him to come out. My new shrimp are worry free.
