White's treefrogs are great
. I've never kept one but when I have the space I will.
The green treefrogs are pretty hardy, too.
I'm a fan of the firebelly toads because they are so colorful and active.
Of course I'm also partial to Marine Toads, hehe
. They are easy to care for but need a decent-sized tank and eat a lot. Very tolerant of handling, too, although I don't suggest picking them up all the time.
I like American Toads though I've never seen them in the petstores here...I caught mine outside. She'd eat from my hands and was fine with handling...one of the best amphibians I've ever had. I really loved her.
Pacman Frogs are cool but not very active. Then again, most toads aren't. Actually, frogs in general are kind of lazy
I could ramble on and on about frogs and toads, haha.
