Bloated Betta. Egg bound? Constipated? Dropsy?

Описание: Attention betta lovers, can you help me figure out if my betta is egg bound, constipated, or has dropsy?

Symptoms:
Swollen belly for about 2-3 weeks.
I first noticed when I got my male betta. They were never housed together but he inherited in her old tank so she was in there when he was floating in his cup during the temperature acclimation.
Her eyes look a little bulged to me. I'm not sure if this is the lighting. I switched from a fluorescent light to LED, and only then did I notice her eyes (upper portion looks white in video).
Her coloring hasn't faded but the area around the swelling is lighter in color, golden to white at times.
No pineconing, it kind of looks like it in the video near the end but in person her scales are smooth. They have black edges which make them look like they're are standing up on film.

Behavior:
Eats like a pig. She's housed with rasboras so I try to feed only them, but she still manages to gobble up all the pellets they miss.
Swims fine, likes to scavenge the bottom of the tank for food.

Attempted treatment:
I thought she was egg bound so I floated her in a cup in my male betta tank for 1.5 days. I didn't see her drop any eggs, but she did poop. I fed her a blanched pea in hopes to make her poop more.
She seemed to be a little slimmer so I put her back in her big tank a few days ago. Now she seems bigger than before.

Thanks for your help!
