I am really interested in acquiring a trio of garters Ive never kept before. I am especially drawn towards concinnus, infernalis, and pickeringii. Im wondering, if all these snakes are roughly the same size and age, and are all the same gender, will there be problems in housing them all together? These three species are my favourite of the sirtalis, and I have a nack for wanting to show off the natural diversity in appearance of similar species. If it would be a problem I would just decide which of the three I want and then buy a trio from there. Another question I have, I have a 30 gallon high, its 30 X 12 X 18, and 8 of the length is divided by glass and silicone as a "water dish". Would this be suitable for a trio of young sirtalis for some time? Any additional information on the keeping of the afore mentioned three species would be greatly appreciated Thank you
