I have a 10 gallon with heater and filter and a 20 gallon long tank with hinged lid. Looking to get rid of they aren't going to work for the project I wanted them for. 10 gallon has 4 extra filter refills. Asking $15 for the 10 with filter and heater and $20 for the 20 gallon tank. Or trade both for two 18 by 18 by 24 vertical terrariums
