I have 2 baby Garters that i am raising right now, and they are fine together, they love each other a lot. sometimes fight over food but other then that they are very happy with one another. Plus i read it is better to house more than 1 snake together. Because it makes them feel a bit safer and they have someone to keep them company. at most I'd say a max of 5 snakes together is fine, if babies than maybe 5-10. lol
