To Catch A Hitchhiker?

[AstroCreep]

Alright...ive got 3 crabs in my tank and they are freaking hard to catch, they only come out at night, there freaking fast. So...whats the best way to catch these things? cus they aint getting any smaller!!!

thanks---

Upright mason jar or drinking glass.
Put some meaty food in the bottom. Crabs go in to get food and cannot climb back up the smooth glass sides.

May take a couple nights - but it will eventually work.

Should i put shrimp in there? or is there a different type of meaty food i should go with? and should i take it out each morning if i didnt catch anything? or just leave it in there

thx

Shrimp is good. Whatever you have is fine.

I would take it out in the morning as to not foul your water. This is more important on a smaller tank tho.
