natural color or something worse?

[elliotulysses]

This is our male Cecil, the one in which I was concerned whether this was his natural coloring or an early sign of red leg


And this is our female Carlos, the one in which I was concerned if she had bloating or if she was just growing up and filling out her shape.
This is a photo progression of her abdomen, eventually the swelling went down but at this point I'm confused if she might be bloated or if this is just perhaps regular digestion habits? It seems she had a lot more fecal material in her holding tank thank the other frog.
