Welcome to the forum...its great to have you here.

You definately need to separate them, but you could divide the 20 gallon into two with a divider down the middle. Standard lighting is good. If you have live plants you would need 6500K for plant growth. Standard CFL's are easy and cheap. As far as heating goes, place your heat mat on the side of the tank not under the tank. They burrow down and could get burned if you place it under them. They also need to be able to burrow to get away from the heat. Which ever heating device you use make sure to use a thermostat so you can ensure you don't overheat and cook your frogs.

Definitely separate them. If you do use a divider, make sure that each side has a temperature gradient; each frog will need to have a warmer and cooler section. If you've read the pacman care articles and some of the other posts, then you're probably off to a good start. Don't hesitate to ask questions. Welcome to the forum and good luck!

I use a 25watt household lightbulb to keep the temp around 80 degrees
