Anyone have a cube or oddball tank you're looking to sell? I'm looking for something maximum 21" wide, 18x18 or 20x20 or so would be great. Ideally 12" high but can work with a bit more height. I don't need a SW nano cube with lid and pump and all that, just a bare tank is fine as I have lids and lights I can adapt if needed, something relatively inexpensive. Otherwise I will go with like a 15 long instead and make it fit lengthwise if necessary.
