20 gallon aquarium in great condition. This package includes everything but the fish. You will have all of the supplies you could need. The tank and lid are in top condition and I installed a new light in the lid. There is also a new heater, corner filter with replacement filters, clean gravel, caves, decorations, floating scuba divers, new and unused plants, cleaning supplies: ph water testing kit, Ick treatment tablets, tank cleaning attachments, magnetic glass cleaner so you can clean from the outside of the tank, nets, syphon, brushes, buckets, etc, etc. I have had fish for over 3 years but now I am unable to maintain this hobby. The cost of everything was $400. I am asking $200. Please feel free to contact me with questions. Thanks.
