Nope, but I attempted .... and let me tell you that Crab is FAST!!!! I tried a small glass with a piece of shrimp in it and he came out and got into the glass and then with Houdini like skills mysteriously disappeared! So I tried again ... and he must have been full from the nice half chunk of shrimp that he didn't come back out.
BUT I can tell now that he is DEFINTELY not a good crab. He is VERY hairy and has HUGE black claws. I was researching crabs and think I may have a Gorilla crab. This guy has more hair on him than I do! I now know where his little burrow is so I'm going to try again in a day or so. Wish me luck!
If I do catch him does anyone want him, if not I'm taking him back to the LFS
... I know they'll take him.
