The frogs should do fine with temps maintained between 78-85 degrees, and only dropping to about 70 at night.
For fish you could try guppies, small goldfish (commets only), or other small live bearers like swordtail platties.
If you could describe what type of setup the frogs are in, or even provide a picture. Also how often, and when you have been offering them food. Then it would be easier for me to offer more specific advice to help you.
