I am thinking of buying a larger tank. I have a 10-Gallon aquarium now. Do you recommend buying a Terrarium or an Aquarium?
I'm thinking about buying a 20 Gallon tank of whatever you guys (and Gals!!) recommend.

Also... How many adult and Juvenile Garters should I limit placing in a 20 Gallon tank? (Can I also add smaller juvenile Garters and Browns with the 2 large Easterns I have?)
Thanks for all the great advice!
Jack
