Second-hand aquariums and cabinets between individuals: bare tanks, nano aquariums, complete kits, fully equipped aquariums and support cabinets. A change of plans, a move? Many aquarists part with their gear as a gift, swap or sale. Find a second-hand aquarium near you at a gentle price, or grab a tank for your next project. Check the watertightness and the condition of the seals before any refill.
