I don't know about your particular situation but if I had an upside down
fish I would immediately be thinking swim bladder. I have never seen a fish
recover when they are unable to right themselves and swim upside down. You
can try, but I wouldn't hold out much hope.
tiny little nips to the fins may indicate bullying but the impact of this
would only be stress, which can lead to bladder infections.
