Prob the best move you will ever make! Tangs are the best by far so much character and personality. You will not be disappointed! As for starting why not start with some nice little shell dwellers like multis. Some nice mid water fish Nigripinis or some Leptosoma. Or you could go for a nice and fun tank with some sandsiffters like Makola or Ndole with some gobies. That's what I have and you never get bored looking at them do there thing. If ya after some multis I got some I'm selling. I'll hook you up. Just send me a PM. Cheers.
