Just got rid of a small Teddy bear Crab that hitched a ride with some LR. I thought he was interesting and kept him around awhile. After purchasing some expensive coral, the dealer told me to get rid of the Bear because they can be destructive. I lured him out with a bit of shrimp on a string and was able to to lift him right on out. Thing wasn't going to let go of that shrimp. Sorry to see him go but between him and my coral, I'm not taking any chances. Anyone else ever deal with these critters?
