Stopped in at petsmart tonight and picked up 2 small thai red crabs for feeders for my mantis. I got ones about the size of a silver dollar cause I want it to be fast as possible and I know salt water isn't there ideal water. Didn't have to worry about fast or having to tolerate sw for long apparently. I dropped them in and went for a quick errand of 45 minutes,when I got back they were both killed and he was eating the last one! Geesh,good they only need crabs once in a while:hmm3grin2orange funny thing ,I had to fill out a contract to buy these crabs,cause they are classified as a pet but fish they sell arent I wander if I make this purchase a weekly thing if they will ask what I'm doin with them? Ill let y'all know.next time ill get a vid.
