Answer
Heather,

Sorry to hear your fish isn't well. Let's see what we can do. First off, the tank they are in is way too small. They each need nothing smaller than a 2 gallon. I am going to assume with the double tank you don't have a heater. Is her stomach bloated looking? Without seeing a picture of her I would say she might have swim bladder. Just in case its swim bladder I will tell you how to give her an epsom salt bath.

1 tablespoon per gal of water. you can use a quart (1/4 of a gal) of water and add just shy of a teaspoon of epsom. Just fill the jar or container with tank water then add the epsom salt and stirred til it was dissolved. Then put her in that water. Leave up to 30 mins up to 2X/day. (start with 15 mins on the first day and increase by 5 mins each time. Make sure you watch her in case she has a bad reaction, but I have never seen a Betta do bad in this water. While she is in that water, do a small water change, maybe 20%. If the problem is swim bladder, this should help her relieve that problem.

Instead of feeding her her regular food, get a frozen pea that has been cooked. Remove the outer shell and feed her the inside of the pea. Then fast her for 24 hours and repeat the pea food.
Let me know if she has other symptom suck as bloated stomach.

I would try the epsom salt bath as soon as you can. If you don't have that, you can use aquarium salt instead. Let me know if this helps, and if not we can try something else.
