From what I have read and from pictures I have seen, apparently red sided garters have meaner dispositions compared to say the Easterns I am familiar with.

These 17 babies seem very competitive and I even broke up a fight when no food at all was involved, they just started biting each other.

These are the first ever red sided garters for me (Thamnophis sirtalis parietalis) and they appear to be a rather aggressive species.

Are they?? any advice from long term keepers of parietalis specimens??
