I'm just curious since most sources say that P. terribilis is the largest dendrobatid and O. pumilio the smallest, but i'm not so sure. Just the other day i saw a trio of imis that were without a doubt smaller than any pumilio i've ever seen. And last month i was visiting some fellow froggers and their patricias/citronellas/cobalts were bigger than any terribilis i've ever seen. Well that's a bit of a lie, the white mints at the last ontario reptile and exotic pet expo were a little bit bigger than those tincs. But you get the idea. Does anyone know what the largest and smallest species/morphs are?
