Hi All, I was just wondering who keeps aquariums as a hobby? I have a 50G, corner, freshwater tank that I have maintained for 9 years now. It has a canister filter and about 30 fish right now. I have Bala sharks, tetras, white and black mollies, platties, a Large Plec (who is camera shy), and my favorite a fresh water puffer named puff. Here is may tank. My living room tank. A few members of the community. Puff the Puffer fish. Puff. Post some pics of your aquariums.
