Two used aquariums for sale, like new, with new filters. Each aquarium comes with a fish net. The black aquarium size is Length 50cm, Width 30cm, Height 45cm. The red aquarium size is Length 45cm, Width 25cm, Height 42cm. For sale to the highest bidder. For your information, I have added extra accessories like stones and nets, and the aquariums are indistinguishable from new ones.
