playing dead

Hi everyone
I thought I would share more things my albino bn gets up to.
last year he was the one that would bury the chunks of cucumber and would dig caves under them and eat them from underneath up.
Well now he has learned a new trick. It started off with him laying on his side against the front of the tank with his head resting on one of the pebbles in the sand. The first few times it looked like there was something wrong with him so I would go check only for him to swim away just as I got to the tank. Now he has stepped up his game by laying on his back and playing dead.
he started to swim out of the ornimental log slowly upside down and when I moved my head to see better he stopped. so guessing what he was up to I got my camera and took this small vid for you to see what I have to suffer with ( prank playing fish!!!!)
