Good luck!
red eyed leaf frogs are gorgeous frogs, so are fire bellied toads, but keeping them together is not a wise choice, I hope the red eyes haven't (as you said) gotten any injuries from the toxins. Good on you for taking the frogs though, and providing them with the correct care needed
I'm sure your tank will turn out lovely, don't stress. It's looking good so far, Can't wait to see it finished
