There is not a thing wrong with being a business. Most of us either do now or plan to sell snakes in the future.
I find it difficult to define a hobby, something one does for pleasure, with a business, something one does for compensation.
I know a guy who keeps a bunch of orchids. He built a greenhouse for them. They're neat. He spends a lot of time with as well as on them. As far as I know, he's never sold one, he's never mentioned anything about wanting to make his investment back or that he wanted to make enough by selling little orchids to buy other orchids.
That's a hobby.
He breeds snakes too. Really nice ones. He sells them for money. I think it's a business he likes a lot but I, just me, don't consider that a hobby. There are different expectations from his interaction between his two interests.
This probably holds true for a great many.
My definitions of hobby and business may be a little more black and white than some.
I'm not claiming I'm right or anyone is wrong, just clarifying and expanding my prior statement.
