In another one of my threads someone suggested that you could place two garters of different species in one enclosure together. They went on to say that males may even be calmer with another male around. I have been thinking about this and doing a bit of research but still have a few questions. First is do you think this is a good idea at all? I know with most other snakes forums suggest that you should not cohabitate for safety reasons. I know that some garters have huge dens with many snake, but is this the case with all species? Next I know that the snakes should be about the same size, but what exactly does that mean? I already have a California red sided and really like some of the radix morphs, so the finding one the exact same size may be difficult as they would be from different litters. If they must be the same size does it make the most sense to wait until they are both of adult size? Although as baby snakes are more nervous does it make more sense to put them together when they are small? I would also assume that growing up together would help when hormones start to join the party. I want to have a planted vivarium for them, what size tank would you recommend for two garters? I just wanted to pick your brains for any information you may have on this.
