Hi all. Haven't had a tank in years. I acquired a flat back hex tank a while back and finally am getting around to working with. The tank is roughly 22 gallons. In the past I've had many fresh water fish. Not really sure what I want. If this was your tank what would you have in your tank? (plants, fish, etc.) just want to get ideas from others to get my mind rolling. I have plenty of time waiting for the tank to go through its cycle.
