Put that fuge on the top.

Passive feed. =D Lots more whole bugs that way, lol. I would advise waiting until you get the new system established - and even then, there are a lot of considerations. Do you want a wrasse, or have one already? They are pod hunters, as are many other fish (pretty much anything you see giving the evil eye to a rock) and will compete with the mandarin for all the pods. It would be a good idea to maybe plan very well for your larger tank (passive feed fuge, I'm tellin ya!) and hold off for now, I know that is dissapointing, but it would be more so to lose the mandarin just before the new tank is cycled.
Thank you so much, cce! I may have already heard about you, lol - we discuss this sometimes on our local forum, where the record so far is three. Someone told me they heard of someone on RC who had a pair for six or seven years - and you are the very first person I have ever bought the "old age" diagnosis on a mandarin from - 7 years doesn't sound too bad to me! Please tell me a little more about your set up, namely -
Size tank:
Amount of LR:
Refugium? Passive?:
Competition:
Feedings? Type? Often?:
Of course, by competition, you could leave out your tang, I am talking pod hunting competition of course. =D
Guess I better spill why I want to know - the boyfriend is pretty obsessed with this fish, like most people, and being that he has me to contend with (I can sometimes be the fish police, lol) he has set up a system designed for this fish. No competitors, passive feed fuge, the works. We are moving this system design over to a 210 gallon, and adding a female - so I am interested to hear about your success and how you managed it! =D Oh, yeah, he is almost at three years now, I think...
