So I'm looking at getting a bigger tank for my box turtle when Petsmart does their dollar a gallon sale, and I thought that once she has more space she might enjoy a tankmate. I was wondering if I could possibly get another type of turtle that can live in the same conditions, or if I should just get another box turtle, or if keeping two together is even a good idea. If it's not a completely awful idea, I was also wondering if anyone has any recommendations for what kind of turtle to get. Morty's a very active girl, and while she isn't much bigger than my hand right now I'd like a sturdier turtle that she can't accidentally hurt. I'd also prefer something that won't grow much bigger than she will, as I'd like to be able to keep them together long term without worrying about someone getting squished.
