Crab molt ID new tank? How do I trap it?

[ilovemarinetanks]

It has at least one black claw. Maybe two.

Does anyone have any tips for trapping it?

Look up a bottle trap.

Look up a bottle trap.

Hi, thank you! Do I have to attach it to a string and pull it out when it gets trapped? I’ll look it up! Thank you!

Shot glass leaned up against a rock you suspect it is using as home base. Bait with small piece of frozen clam or scallop or shrimp. If you have hermits, my catch them too

Hitchhiker crabs make interesting pets, in their own separate container of course.
