Houdini has been taking small peaces of shrimp off the end of the stick , was getting him to come out more every day, till today, today I had a set back, today he came out all the way started wrapping around the food and one of the live grass shrimp that i am always fighting off when trying to feed him, bit him and bit him hard , he twitched a bit from the bite and went all the way back in to his den and would have nothing to do with me after that ...spent the next hour removing all the live grass shrimp from the tank, I don't think he liked to eat them any way.
