trying to do what i can only describe as eat her bottom?
Hee hee...sorry, I shouldn't laugh.
I don't have lots of help to offer, except, are you feeding floating or sinking foods? Or, more specifically, does your female feed from the surface? Gulping air while feeding can cause swim bladder (i know this doesn't help now, but might help you decide if it's swim bladder or not).... Have you checked out the pinned disease info?
Some medications do
claim (not sure if it is true) to help with swim bladder, if you do decide that this is what she has, you may be able to treat- the sooner you get to her, probably the better.
I'd say your male is hassling her to mate, are there lots of plants/hiding places in your tank? If you end up seperating them with your breeding net, please take him out and leave her where she is....Stress will make her feel worse.
Do you have salt in your tank? (i probably should know, cos you've posted about your tank a few times. but sorry, i can't remember).
I wish i could give you a proper answer, but don't worry, i'm sure someone will be along soon who can.
ps, you could try feeding her shelled peas...
