Hello everyone!! I live in Magnolia, Delaware and we just rescued a little crowntail from Walmart and we have everything we need to give him a good home, except a heater. We have Aquion 10 watt in both of our tanks and they work very well. However if you do not have that kind of heater that is fine. We are just looking for a less expensive heater. If you have one that will work in a 1.5 - 2.5 gallon tank, let me know and let me know how much you would like for it! Thank you very much!
