Hi Laura,
Congratulations. They are sweet, very calm and hardy frogs that will live a longtime.

Yes you are right --"I see on the white's care sheet that 85 degrees is recommended"

Temperature............Day: 85 °F Night: 68 - 75 °F As Carlos has mentioned, maintaining this range will depend on and be affected by the light you choose. If you have real plants in the tank , you will need a full spectrum bulb for the plants. You can pick up a "Philips" plant bulb at Home Depot for about $4. They work fine, but do give off heat. Get yourself a few good thermometers ( even one found at ie home depot, waterproof is a good addition to your supplies )

Here is a link to a whites cares sheet and some very good references.

I would like to mention the need for a quarantine period. Sorry, no one likes to hear this. Some instructions are below.
Plus, a FF search will validate the need for this with any new frog(s). It is so important when they are new - to keep an eye on there food intake, poop ect. If one is ill or has parasites the other will as well. If your frog is wild-caught, it's a good idea to have a fecal exam done by a herp vet.

I suppose since they are already together ----they could be quarantined together, however it is ideal to separate to monitor properly.

Of course , I'm sure you know the importance of de-chlorinated water - only - for their soaking dish.

We would love to see some photos !
