I see. Well I'm pretty new to this stuff myself (and I only have one WTF in my viv) but I've read that some people feed their animals in separate enclosures. I'm not sure what kind of stress "re-locating" each frog for her daily feeding might cause, but I would imagine hand-feeding it 'cricket bits' might be as stressful (if not more) Almost akin to force feeding.. If your "skinny" WTF is a shy eater, maybe you should consider a separate viv for her / or conversely, a separate viv for your aggressive eater? That way you won't have to handle them daily or separate them for meal-time. I really like bowl feeding because I can monitor exactly how much (or little) my little pal is eating. She's also "thinner" than I anticipated for a WTF (although she's still young) AND lately she's been eating exactly two crickets each night. No more, usually no less... Again, I expected her to gobble up everything in sight based on what I had read about Dumpys being voracious eaters.. Anyway, I'm rambling.. but - your WTF looks okI would try to get her eating "live" crickets though.. by all means get many opinions though... I'm very new!!
