I was just given an aquarium from a friend. It's a Hagen brand, and has a canopy without lights. It's an odd size, I can't seem to find much info on it, and I'm having trouble with ordering a canopy because of the odd size. Dimensions outside to outside rim are 29 3/4"x 12 1/2". Tank is 16" from floor to top of rim. Can someone tell me if this is a common sized tank and I'm just measuring wrong? Will the standard sized accessories work?
