After building a habitat - 10g tank, plants, water, hidey hole - for an unknown variety of garter snake my little one insisted on keeping. Well, we just found another snake. It's small ~ 7", brown on top, yellow on bottom and very quiet. I was hunting worms for the other one when I found it. Can I keep them together? The garter is eating worms 2-3x/wk. I'm running out of pet space, but can't take the drama of trama should one devour the other. THANKS!
