I keep all elapids you have listed apart from Dugites and Desert adders. They are all quite exept the Pilbra adder is a bit snappy. HOWEVER!! They require your 100% attention when they are being fed. The southern adders lay motionless until there rodents are offerd then release an explosive like strike that never ceases to amaze me. No second chances for complacency with these guys!
So what species do you think would be best to get as my first elapid? and what in general are there temperaments like???
