40 Gallon Tank Large pregnant guppy seems to have swim bladder issue

[Ahormann15]

I was about to clean my tank when I noticed one of my large female guppies swimming upside down and crazy. Seemed fine this morning but looks bad. It is probably her swim bladder but I don't know what to do to help. Please help. Thank you.
Never mind she dead.

I'm sorry for your loss.

Generally with swim bladder problems, you'll want to try fasting the fish for a couple of days and see if it clears up. After fasting for a couple of days, if it has not cleared up you may want to try feeding pieces of thawed frozen peas cut into bite size pieces with the skin removed. (I know thawed frozen peas sounds like an oxymoron, but you don't want to use canned peas due to being packed in brine and you don't want to feed the pea while it is stil frozen).

Another option is to try feeding some daphnia.
