Toads (Southern, Western, American...) are generally great at room temp. Although they are major burrowers. Wood frogs will do well at room temperature, but they are fairly difficult to keep alive in captivity, they aren't highly adaptable, and they need a pretty elaborate, naturalistic set-up. Pacific Chorus frogs and most other frogs from Southern Canada/Northern United States do extremely well in room temperature conditions All of these options need 10-15 gallon minimum for one frog, and 20 gallon would be excellent for two!
