Thanks April. I don't know much about Hog Islands or other Boas for that matter but I should be up to speed before I make a purchase. Do they need ambient temps on the same line as BPs (high 70s)??? I'll have a 3x1x1 pvc enclosure w/ a UTH & Tstat but sometimes the ambients could dip. That's why I have an AP cage w/ an RHP on the way.
