I'm wanting to start up an indoor water garden with some fish, but I can't seem to find a good sized decorative tub anywhere that would be suitable. Anyone have any links? Looking for something relatively straight sided, round or square, preferably, and somewhat nice looking on the outside, roughly 50 inches across, more or less, and about 25 inches tall, give or take. Plan on planting horsetail rush, maybe a shade loving iris or waterlily and keeping a few comet goldfish.
