I've got a 29 gal
w/ a bluegill, pumpkinseed sunfish, and 3 crayfish, all caught in northeast Ohio. My filter is a Fluval C3 and things have been going well. 12 years ago I bought the tank and kept red-bellied piranhas. Back then I didn't fully understand what all was going on inside the aquarium. A few months ago I decided to start again and did a lot of learning. Now, thanks to all the information in these forums, I have a healthy aquarium!
