They can be kept similar to a corn, but you need to be aware that the bite has more punch than the average western. I know 2 people that have been hospitalised by them with palpitations and needed to be cardiac monitored!!!
i got tagged by a young male of about 2' long and my thumb doubled in size and throbbed for about 24 hours then went down.
I have one pair that are placid, and an extra female that hissies, hoods and musks as soon as you open her viv, but she has never bitten, she is ltc which might be the difference, the other 3 i have are all cb.
Cool snakes though, more closley related to the elapids than westerns i believe.
