Not much, but I finally got an aquarium for myself. It is a 37 gallon that I got from my mother in law for free (she wanted it out of her house). I have a heater, and all the basics. I know it is small, but I am wanting to get a few fish for it. I am really wanting for a few bottom feeders or possibly only one, and a couple cichlids. What would you do with this set up?
