My betta seems to think s/he is a dolphin. The other day I heard a splash in his new tank (which is wonderful, perfect temp., very clean, s/he loves his plants) Tonight my boyfriend started laughing and said that my fish jumped out of the water. I later caught it in action. My little Dancer will just sit at the surface of the water and then randomly jump/spazz out and fly above the surface. And then he'll just go back about swimming normally.
What is going on?
