Fish Fanatic
One of my Black Widow Tetra is dangling nose up about two thirds of the way down in the corner of the tank. If I tap on the glass he darts away and swims normally but soon comes back and resumes the same behaviour. I think I've seen him, or one of them, do this before but not constantly like this. Swim Bladder Disease seems to be nose down swimming, or is this a variation and what's best for him.
