That's awesome. My pair are currently residing in a 120 gallon tank, but are either being upgraded to a homemade 500 gallon indoor pond, or a 290 gallon preform pond (that will also be indoors.) I'm looking forward to getting them in to something larger. We're about to move though, so things are on hold for a few weeks. No reason to finalize 4000 lbs of water, just to break everything down in a couple weeks.
