Cohabitation

A group is possible. Water and garter snakes are the exception among colubrids: they lie together willingly and can be kept in groups. But the feeding accident remains the risk here too — so always feed them singly, ideally in separate boxes, and only house animals of roughly the same size together.

Notes

Very tied to water – a large water basin is used intensively. Live-bearing, diurnal and a keen feeder; easy to breed.
