This aquarium is 20.5 inches tall, the usual 20 gallon tank is 16.5 inches tall. This aquarium holds over 27 gallons of water. It is on a nice stand made of oak or pine, I can't tell which. Everything works as it should; glass top, LED light fixture, UV filter, Aqueon mechanical filter, air pump with bubbler, thermometer, and some floating plants. There are two dark angelfish and a couple of catfish, all healthy. Purchaser must disassemble and take the aquarium along with all the peripherals. I can assist with the process.
