I am going to be purchasing my first woma and am confused about the proper substrate to use. I was going to use aspen bedding like I use for my corn and rat snakes, but the person at the store I'm buying him from said to use sand. Hmmmm . . . am very unsure about using sand, possible impaction and all that. Of course, he could get impacted from bark also, but I feed all my snakes outside their tanks to minimize that risk. Does anybody else have an opinion/preference?
Also, I have yet to find a detailed care sheet for womas. From what I've read, it seems like the set-up is the same as you would use for a corn or rat. I know they can get aggresive during feeding. Is there anything else I should know?
I'm probably sounding like a total worrywart, but considering how much womas cost, I'd rather be safe that sorry!
