I'm in RTP, and I'd love to have him in my 40 gallon. I work a lot and as a result my spare time is slim, would you by chance be willing to meet halfway?
FWIW, I have never seen a sailfin get to be 2 feet. I have 2 adults now, and they have maxed out at 12 inches. This is with huge water changes (180 gallons every 1-2 weeks). I have seen commons get to 2 feet though.
