She (I think) floats upside down like that so scope out the next place to forage. She adjusts her fins to make sure she stays level. I was worried at first, but after close observation it's definitely being done deliberately. If I adjust the fllow of the filters, is messes her float plan up and so she will figure out where the next best place is. Fish is goofy like that.Ummm...Jaysee, why is Fish upside down? Is he always like that?
