Can understand with the D&M's fantasy horned frog and Kim thomas's abilno, beautiful! But they're like a fashion accessory rather than a display of activity, unfortunately. Although I suppose they're active at night if you use LEDS to view them, especially the cranwellis. Giant African bullfrogs though! Or Colorado river toads if you're into big frogs. If you've seen them in flesh Cory you would be amazed. Massive, rhino-like toad means awesome! Dart frog also sells them but a bit different in care. Definitely a good idea to resist the temptation and keep it to a limit, easier to pamper those select individuals, I have gave a few away myself.
