We finally got around to getting fish in the tank we got Jenavieve for Christmas. She always loved watching them in the store so we thought she'd enjoy them at home too. We were right! We have the tank right on the floor so that once she's mobile she can get to it herself (it has a child lock on the lid) and she loves laying in front of it, watching the swim around. The woman at the store recommended 6 fish to start, and then more in a week or so if we want more. We got some mollies and some platies because they are colorful and a bigger size than a guppy so they're easier to follow.
