The Yellow Tang is the least demanding of your tangs, so you could probably keep him longer if you find homes for the other two. I understand your liking for them. I also love tangs, but I don't want a tank big enough to keep them! Try out the Flasher Wrasses...they'll grow on you. If you had some sand you could get a jawfish, and they are really fun to watch. They are constantly renovating their burrows. Very cute.
You could probably sell your pumps, or keep one for a spare in case your pump ever breaks down (it will happen). Which reminds me...I need a spare too.
