So like I said in my introduction post, I'm looking into getting a garter, or a few if I find a couple I'm in love with. However I know almost nothing about the different species, so I was hoping you could help me out. So far I have two corn snakes, but I have worked with ribbon snakes, garters, boas, and other larger snakes.
I would really like at least one garter that is blue, I was looking at the neon blue red side, or a blue stripe, but correct me if I'm way off. I would also be interested in other colors, I'm convincible.

I would like something that isn't too aggressive, aggressive when held is okay, I just want to be able to do stuff in the tank without it flipping out too much.
