Shani, my little girl betta, has a very particular habit when she's sleeping. When she breathes in, it's extremely hard, and she actually jumps out of the water a little ways, and makes a loud slapping sound. She does this for hours, and I don't think it's normal, as none of my other bettas do it. I have absolutely no idea what she's doing, but it worries me. Should I be, though? She's done this before, but since I moved her tank, I hear it much more now. She seems to be fine, with no lumps, fungus, or fin rot... just this odd way of breathing. Any ideas?
