Bad idea all around. Most hitch hiker crabs are predators. Unless you can 100% ident them... Flush them or feed a hungry trigger.

Lots survives on live rock. Live rock is shipped internationally wet but not in water.... Imagine the weight of 1000 lbs of rock IN water.

20 minute car ride is nothing.

Good luck.

Fair enough... I'll have to stop by the grocery store and grab some u cooked shrimp

yeah I have to agree I would try to keep them out of your tank, the sump is ok I think. but keep them away from you display, you never know they might grab a fish for a snack at night or coral..

Unless I have a crab living in a coral and doing damage, I almost never remove them. Unless they're big, or you have really small fish, they're all mostly fine. My rule is unless they do something bad, they get to stay.

Ya don't have fish yet ... Still doing the initial cycle it's the corals I'm worried about cause it looks like he might have nipped my chalice a little bit... Any other baits I could use

lol good rule, my emerald crab is going to be getting banished to the sump once I upgrade my tank, he likes to taste my Zoanthids.

shrimp will work for sure. I put shrimp in a net and left it for 20 minutes and pulled out a 3 inch bristle worm!! I put him back but its was neat

[Kgrizzle]

Ya I like that rule to it makes complete sense ... Let nature do its thing and u see something corrupting ur peaceful and tranquil harmony remove it

As for the shrimp, do u think think mysis in the pantyhose will work?... I'm debatable whether to keep them or not... I just don't like the look of it... I know they are good cleaners but not pleasant looking

[Nano]

yes mysis works, everytime I feed my blenny my crabs and bristle worms come out to eat too
