I've lost 4 danios over the course of the past week and I'm worried at least 1 more may go down this path. The 20g tank only has danios and a dwarf frog.

Added new driftwood about 5 weeks ago, tied existing plants around it and all seemed fine.
Weekly 30% wc with gravel vac due to messy adf
It began with Mean Mean Fishy Face, the tank bully lady, who was big like before laying eggs. After her stomach deflated from the eggs, she had this odd sail shaped mass in her stomach. I thought maybe she was a bit fat and overfed.
She stayed with the notch for weeks, still ate, no other apparent problem. Then she started hanging out towards the bottom more often and other fish took over her usual territories. After a couple days of not eating and hanging out in the bottom half more, another danio started hanging out at the bottom. I qt'd both to a hospital tank filled with tank water and dosed with kanaplex.
The second fish to fall ill died overnight with no other sign or warning. Mean Mean seemed to be doing well. Her stomach flattened out, still no eating. After another day of looking better, Mean Mean died and had a large bruise under her skin only on one side (yellow fish photo) right after.
Fyi, I did daily 50% WC in hospital tank adding tank water and redosed kplex for added water only. Temp and other parameters matched between the tanks. I tested a/n/n twice daily to confirm all was well.
After that, 2 more fish in the main tank got sick. Both males developed the same sail shaped notch on their stomachs (pink fish photo) and started laying on the bottom. This was more sudden than the others.
I sanitized the hospital tank, tried again with both of them on kanaplex. After 48 hours of looking better, and the notch smoothing out, they started laying on the ground in a c shape. They'd occasionally try to swim but would have no successful direction and would lay in a c shape on the ground. They died quickly within an hour of this behavior (before I could figure out if they could be saved or should be euthanized).
Now, my last female in the main tank is swoll up like she's with eggs for a few days now (no pineconing or dropsy look), but she's not eating, towards the bottom, and I worry her eggs may be hiding that sail shaped notch. There are 3 other danios in the tank seemingly normal, ironically the weakest fish between physical deformities from birth or being juveniles, and an adf.
I can't tell what this is, how to save them, if the others are done for, how to clean/save this tank, and ultimately how to treat them all. Thouhts please?
