Well, with a 1 gallon you really can't cycle it. You can, but there isn't enough surface area for the beneficial bacteria (BB) to grow. I have a fully cycled 3 gallon and it's working great for my guy. The 1 extra gallon really does make a difference. It's like the difference in living in a closet versus a small bedroom.
Petco and Petsmart have the same tank you currently have but in a 2.5 gallon and 5 gallon. I believe it comes with a filter, too. Petco sells plain glass tanks (no lid, no filter, just the tank itself) for pretty cheap prices. Right now they are having their dollar per gallon sale on tanks 10 gallons and up with a membership card but that's in store only. I have the Marineland Crescent 3 gallon from Petsmart which I love. Only thing I don't like is the lid, I can't get it to stay on properly so I just kinda set it on top to help with evaporation and so Frederick can't jump out.
