Small but big?

I just recently bought an aquarium at Petco. I've been to every pet/fish type store in my area and haven't seen one like this. Has anyone else out there bought this type of aquarium. It's exclusive to Petco, name is Aquatic Gardens, its a 6.6 gallon Bookshelf acrylic aquarium. I'm not sure but I think its 9 or 11 inches deep or 9 or 11 inches tall and either 20 or 24 inches long. It's a great looking aquarium, has a big look to it without all that size. Comes with an outside filter that's wonderfully quite and a flourescent light, hood ect. I'm just curious if I'm the only one that has one of these aqauriums. Let me know if you do and if you've had any problems with it? MLJ
