I guess to start you'd have to ask yourself what is your goal with having snakes, do you want pets only? Do you want to breed? Do you want to handle your snakes a lot or just have displays? I have 20 tubs in my rack and I'm currently going through and selling some and buying more, my goals have changed since I started keeping them. I actually just sold a male adult Woma python LOL. I planned on breeding him but changed my mind and decided to go with super dwarf retics instead, mostly because they bring more money and have a lot more color morphs. Plus my tubs are almost too big for a Woma, but I think would fit a SD retic nicely. I also have a bunch of king snakes, really cool but breeding them doesn't bring much money, and most don't have that many color morphs. Plus I'd like to go with mainly one type of food - rats. With my smaller king snakes they need pinky mice and I want to get away from breeding mice and just stick with rats. Even with 20 tubs there are so many snakes it's difficult to decide what to keep and what to sell and what to breed, all of them are like family pets to me. I'd suggest watching some videos on YouTube or going to the reptile shows to see what's out there. For me, to see the snake in person really changed my mind about what I wanted.
