My wife is against the black stock-tubs and wants something clear, so as a temporary measure, I upgraded them to this;
http://www.containerstore.com/shop/stor ... d=10010965 It's small and obviously not ideal. That's the larger version of what I was using before. The construction is the same, and they told me it would hold water at the store, but I'm a little worried about it holding.
I also purchased a zoo-med 511 canister filter for 75 gallon tanks, which I intend to run in conjunction with my old repto filter. Hopefully this will keep the water nice and clean for them whilst I hunt for a larger proper aquarium.
Being in NYC, it's difficult to find a suitable tank for the longterm, but I have it on authority that the Petco in NYC will be doing another dollar-per-gallon sale soon and offering a 60 gallon tank on it, so that's what I have my eye on.
