Chondros are way easier than ETBs! ETBs are far more onery in temperment though I have had some cantankerous Chondros. ETBs feed far less...overfeeding them or feeding too large a prey item is bad news for them long-term. ETBs require much more care and tolerate far less in husbandry "mistakes" than do Chondros. They are almost polar-opposites in this regard. Anybody in here can write volumes on this but in reality the only traits they share is their coloration and arboreal nature.
