I am also looking to SELL two tanks. They come with filters/heaters/light/decor that are currently in them.
Petco 2.5 gallon desk top aquarium: Includes two silk plants, filter, thermometer, floating plastic water lettuce, black gravel, and zoomed betta heater. Asking price: $30
5 gallon glass aquarium: Includes thermometer, filter, hood with light, black and white gravel, offbrand preset heater (I think it's a tetra but am no longer sure), one silk and one plastic plant. Asking price: $40
Please understand that unless fish are adopted out tanks can NOT be sold without the adoption of a fish.
