snakes should never be put together that is a rule as the will eat each other at one point and never house your baby cors in to big a vivarium as this can freak them out they must be put in a small tank you can get small plastic tanks quite cheap from your local pet shop these are very usefull for around the first year of there life as corns do not require any uv lighting or any lights at all a simple under tank heatmat is the perfect option and control the temp by using a thermostat
