Hi,

they look just fine to me, especially females tend to be quite chubby if fed sufficiently. So the amount of food seems to be adequate, but I wouldn´t feed them exclusively on bloodworms. It´s much better to alternate their diet with other live or wet-frozen foods such as glasworms, black mosquito larvae, artemia, tubifex, daphnia, chopped earthworms etc.
I´m sure your frogs will appreciate the new setup
