I have this male motoro for little over a year since it was a pup. Not too long ago I saw it do the wildest thing. It swam to the top of the tank and then inverted itself to cling the the top of the water tension. The funnest part was that it just stayed that way and float around the top of the surface of the tank with it eye balls sticking out of the water. I will have to try and get this on video as I never heard of this before.
