Local crabs?

[pokerfish]

I suspect this is a dumb question but...
Can you acclimate local crabs from Quincy bay to a reef tank?
We get tons of little ones as the tide goes out. My guess is that even if they make the temperature change they probably devour corals?
Just wondering if anyone has done it or if it’s doable.

Some of them you can. Here in New York I have added every kind of crab there is. Most like blue claw crabs which I will catch today and eat will acclimate great and eat everything in your tank, including your cat.
But they have no problem and will be full grown in a year.

The small hermit crabs will acclimate but may only live a few months. The small green crabs will live forever and "may" not catch your fish as they live under rocks so you will never see them. Fiddler crabs will drown as they are intertidal creatures and need to live half their life on the sand.

They never lived past a month for me. They need cooler waters then our reef tanks, same goes for local snails, but, our store bought crabs love snacking on local snails.

Added some small local hermits to one of my tanks this weekend. They lived about 6 hours before the mantis shrimp tracked them all down and ate them
