This 20 gal aquarium is very nice, and has built in lighting in the lid, have heater filter, gravel, all you need. Even a matching stand! You won't find a better buy out there for a decent tank. The photos show a picture of my fish inside which are a breeding pair of discus, (they're not included). I have been considering perhaps selling them, but not decided yet. Breeding cone in the photo is not included. This would be an ideal tank for someone with a small space as it doesn't take up a lot of space being tall rather than wide. It's a nice looking tank. Given the very cheap price, it's firm.
