I have been haunting the site since I got my new aquarium two weeks ago, but finally decided to register because you all provide invaluable advice.
I have a 10-gallon aquarium with AquaClear 20 filter and heater. There is only one resident, a blue/red betta named Bobby. I had him in a tiny betta tank when I first got him almost a year ago, but realized he should have more room to roam. (Better late than never.) I've been enjoying setting up the tank and watching him enjoy all the room and cleanliness he has now!
