Question about mixing frogs in a vivarium. How many & what species can be mixed?

They frogs you listed would make horrible house mates. They are all from various places and ecosystems from around the world. Being from different places and being wild caught they will be carrying exotic pathogens that the other frogs in the enclosure will have no immunity to. At least two of them are known to be toxic.

The general rule is that you don't mix species, especially for beginners. Its just not a good idea.

Undertank heaters really don't work well for amphibians as their enviroments are generally really wet to moist and that can cause a thermal crack if a heater is placed under the tank. Mounting the heater on the side is better.

Kurt has it right. Mixing is just a bad idea.

Since you're new Firebelly Toads make great starter frogs. They are very hardy and would love a set-up like the one you mentioned. I have four in a 29 gallon like the one you're going to do. Plus depending on what you keep your house you wouldn't need an undertank heater. Most people keep their firebellies at room temperature.

Thanks for the quick responses and I will change the way I was gonna put the heater, but I'm kinda set on getting more than one variety. The tank is long and tall and it could definitely take at least two types of frogs, the toads in the bottom and something to hang out on the top, like a tree frog. Are there any two you could recommend? I like the whites frog as well, would that be a better choice than the fire bellied toads?

Again keeping multiple amphibian species will most likely end in disaster. They will be cross contamination, in other words they will be poisoning each other. Do yourself and more importantly the frogs a favor, don't do it.
Besides cross contamination, there can be cross infection, and some frogs will eat other frogs. White's definitely grow big enough to do this. If a White's were to eat say, a fire-bellied toad it would end with the deaths of both frogs.
I think a colony of dart frogs is good for that sized tank, but as a beginner I would not start with them. If you want a semi aquatic set-up you really can't beat fire-bellies. Mine are forever entertaining.

hmmm.. fire-bellies. I have extra 5 and 10 gallon tanks. Where's the care sheet?

We don't have one (yet).

[Ribbet]

Ok, so I can't mix them, but are fire bellies really the best choice? what about Cubans or green tree frogs or the white's. I know I'm just a beginner and all that, but I don't have room in my place for more than one tank and whatever frogs I get first are probably gonna be the only frogs I have for a while.

[JeffX]

I myself would love to have a tank with multiple species in it, but I won't. It's not good for any of the frogs involved.

You wouldn't be disappointed in Firebellies either. I can always hear mine, and they are very active.

45 gallon is pretty big you could keep something like a colony of dart frogs.
