I live on the Gulf Coast and have an 55 gal. sw tank. I recently went and checked our crab traps and an aprox. 3" shrimp was on it. So for grins I brought it home and placed in my QT tank for a week and then put in the 55 tank. He is a cool addition. Doing great after 1 month. Great clean up member. Has anyone else ever heard of or done this?
