OK, we'll go get him a companion tomorrow. Thanks for telling me that.

We are keeping him in a tank. We kept Perrie in the same tank. Here's a pic of it when Perrie was in it:


I'm talking to my mom as I'm posting this, and she said there were only one male and one female gerbil at the PetCo we went to. Would it make a difference if I got him a companion from another store?

Thanks for the advice.
