Out of all common frogs, clawed frogs, whites treefrogs, gray and green treefrogs, and firebellies are the best.
Clawed frogs are wonderful. African clawed frogs go into feeding frenzies and use their claws and rip prey apart if its too large. They will eat non living food and dig for morsels in the substrate. They are intelligent frogs, and can respond to sounds when its time to feed. Everytime I turn off my filter, my frog comes to the top. Skippy also responds to the sound of splashing water. With enough time, they may even respond and sit in your hand near the top of the tank! They are active, especially in the evenings and swim gracefully. Males also have an interesting call that is VERY LOUD, but is pleasant to here. They do a cool mating dance and do loopty loops when they breed. Unfortunately, they need the largest aquarium possible. They are also very good at escaping, and difficult to restrain if out of the water. They are also poor candidates for beginners wanting to "decorate" as they are incredibly strong and uproot everything, even rearranging rocks. But they are hardy enough to be kept in a pond during the summer, as long as you bring them in when temperatures drop to 40 degrees and don't ever let them escape.
green and gray treefrogs are good. Although less active during the day, they are very active in the evening. They are cute and very hardy. They are not destructive, and can be kept in nicely planted tanks.
Dumpies, or whites treefrogs are awesome. They are pretty inactive, but are very hardy, cute, and easily tamed. If you're a photographer, they are the best frog to take out and photograph (just don't do it all the time to cause stress) Although massive, they can be kept in some nicely planted terrariums with care.
Firebellied toads are great, except when they turn a yucky olive green. They are not destructive, hardy, and handsomely colored. They make a barking call, and pretty active. However, don't believe that they are 100% diurnal. Sometimes they may stay in the back all day, and then come out right after the lights go off. It goes in cycles, but they still provide lots fun, especially when they hump each other and nearly drown one another!
