Limp, they look like mine, honest. I noticed that my female bulked up like that right before they started spawning, so I wonder if yours is full of roe. . . or bloodworm!? I got really nervous about her, thinking that maybe she was getting more to eat than Frecks (but I watch them eat, usually, and mine seem equally bad at finding food UNlike your female), I even fed Frecks by hand a few times and fasted her - no change. . . then they started to mate.
I wonder. . . if maybe . . . the 'aggression' is pre-spawning behavior that I've never read about or seen? OR if maybe he's a hair too young for spawning, but she's impatient, lol. I dunno... maybe Gizzy can help.
Just to make you feel better, look at their bellies. See how they go like this () BOTH of them bow out slightly along the sides - not IN. One is obviously a bigger frog all around, but neither of them are starving, or even hungry, so I think you're fine :) I've seen frogs before who's bellies go like this instead ) ( and THAT is not okay.
