I already did this experiment because i figured in the wild, some predators wouldn't eat cleaner shrimp (or other cleaning fish/inverts) because they did the predator a favor and would clean them in exchange for their life. So i took a wonton soup pt container, drilled holes in it and stuck a cleaner skunk in it. Oh and i stuck it in my predator tank which had a snowflake eel, voliton lion, niger trigger, a bursa trigger, green wolf eel, list goes on. But anyways, after a few days in the container, nothing seemed to pay too much attention to the shrimp at all. Slowly i began to release the shrimp. the lion didnt pay any attention to it, nor the eels, but as soon as the niger trigger saw the shrimp, he jumped on it like a fat kid on cake. I saved the shrimp before it turned into dinner, and now he lives in a nice 125 reef instead. just thought i'd put in my experience
