well there's the blotched, barred and some others along with the smaller cousin, the californian. they have great personality and care similar to every other salamander basically cept that they eat a lot more!
well dont count on the pacman frog using all of the cage....
idk if you want a active animal.
the frog will sit in one spot then move to another.
make sure the water dish is big enough for him to find it. (lenght wise)
