I don't even want to think about the upkeep on a 240 gallon tank. I keep a 45 and I always think it's a good bit of work but 240 gallons sounds insane. That being said, I would love to put about 200 little South American tetras in there just to see large schooling behavior. I've always felt that parameters were easier to maintain the bigger tank that you have though. Did you find that to be true or was it about the same? Also glad to see folks talking fish on here, would love to get this section going!
