It was so bad I flipped out one day I was so frustrated I could not catch him I took a barbecue fork and was stabbing under the rocks to try and kill him !!! Soon as I stopped he would come right out and start spitting sand all over like he was taunting me lol !!! I really lost it that day and the sad thing is he was a great fish everyone loved how he scooped up sand and spit it in to piles he would make a new house every night !!
