Awesome animals, on the whole calm as adults (when properly socialized) and nippy as babies. I keep a small group of exasperatum and horridum. With Najakeeper posting pics of his heloderma, I thought it may be times to fly the colors.
These are easy animals to keep - no UV, infrequent feeding and no huge space requirements. Yes, they are venomous and yes an envenomation is nothing to laugh at, but with proper handling this risk can be mitigated.
Exasperatum:
On of this year's Horridum:
On of these days I'll get my wife to snap the shots with her camera. The iphone + my crappy camera skills do not do these animals justice.
