Looks normal to me. My females get more plump than that when they're about to lay eggs. I had fry that I thought were eating too much but about 6 of them laying eggs in different areas of the tank. In my experience its normal but if its not swimming like normal thats unusual. My fish swim the same but are more aggressive.
Her tube is down for sure give it max 3 days and if she doesn't lay you might have an issue. She might absorb the eggs which is normal if there is no male. I had females lay eggs all at one time for one male.
