how much harder?

[j_h_smith]

how much harder is it keeping a boa compared to a ball python? or different? are they more aggresive or less? any other key points. also how do breeders manage with the electricity bill, or is there a trick to heating up snakes with low cost electricity?

As an adult, they will obvioiusly need a larger enclosure. Their food requirements will mean larger rats (depending on type of boa). Any snake can be agressive, it's more of an individual thing. The usual husbandry are close to the same. I'd recommend looking for a good care sheet on the boa that you're interested in.

Electric bills are what they are. If you can't afford a larger bill, don't breed snakes.

Breeding snakes will never make you rich. If anything, they will cost you money. If you think you can make money, you're kidding yourself.

Good Luck!
