I get so mad that people sell corn snakes and say you can keep them together. It isn't fair to the snakes or the owners.
I'm so sorry that you got misinformed. I promise you that keeping the snakes separate will be easier for you.
For baby corns (up to 2 feet) here is my set up:
Not pretty, I know. But it works until you can buy another nice home. Corns also love the tight space. I think it makes them feel more secure and less stressed.
Here is a pic of an individual home:
They like small hides that they fit tightly into, and they love those water dishes because they can hide underneath them.
These are plastic shoe boxes, they cost $1 most places. I drilled holes in them for air. SMALL holes, so the snake can't fit its head into the hole.
I use binder clips to hold the lids secure. Or, you can spend $2.50 and buy latching shoe boxes. The baby snakes will escape if you don't clip the lids on.
I would recommend putting one or both of them into shoeboxes until you get another tank. Of course, I keep my adults in bigger plastic containers- but that isn't as pretty.
Get a probe thermometer ASAP. $7-10 usually. Put the probe at the bottom of the container, right above the heat. This is the hottest place the snake can get to. That spot can't be above 85°.
Until you get a probe thermometer, I would put something (like a thick towel or ceramic tile) between the UTH and the snakes. Or, just leave the heat off.
You are probably wondering how you are going to heat two homes with 1 UTH.
Stick the UTH BETWEEN the two homes, touching both sides. This will be fine. If you do this, put the probe thermometer at the hottest point in the containers.
Your snakes will grow, and you will eventually need at least two 20 gallon longs, or two 41 quart plastic containers.
If I were you, I would sell the 30 gallon and just save up for two separate adult-sized tanks.
Thank goodness you found this site. I hope your babies start to do better!!
