today i went to the LFS to get some live food for my mantis well i was looking and the guy there gave me 4 camel shrimp for 2 bucks a pop since i was using them as food. so anyways i gave my porcupine puffer some which he loved and i gave my mantis shrimp 2 in hopes that he would battle and eat and even get a little exercise...well anyways he obviously didnt like them in his tank but instead of attacking and killing them he abandoned his burrow and is now on the other side of the tank behind a small rock a little bigger than him..whats up with this is he protesting or is he really scared of these things?
