We played like that all the time. It stopped yesterday. He got me well enough to know better. He is from the first ones WH brought into the US. I think it was in 2005 or so. He grew slow when he was small but has snowed no sign of slowing down. It is the smartes fish I have ever owned. He can flip post over to get fish out to kill, If he see's a loose part of a divider he will work on it until he knows it down. They are a great fish.
