She's having trouble swimming, kind of always aiming her head down to swim. She is always swimming on an angle, and staying right near the surface. She's not glass surfing like she has since day one. She just tries to go halfway down her tank with her head aimed down, then swims horizontal with her head still down, then goes up for air. She's also going up for air way more than she ever has. I'm super worried, and it's breaking my bloody heart watching her struggle... She's never not come to see me when I go over to the tank, but she's so intent on trying to swim properly she's acting funny.
Her gills look fine, she's got no weird bumps, no cuts, no swelling (apart from her tummy because she just ate 10 minutes ago), no specs, nothing... I don't know what to do for her...
