Congrats on the cycling of the tank. Im new to this hobby as well so Ill let the profesionals be the final word. What are your water paremeters. As long as your nitrate and ammonia are 0 I think you will be fine. Your nitrate should be 0 but mine is higher and my fish seem fine. "Im still doing 3 day PWC
to get it down" As far as fish go, we need to know what kind of tank you want in the end. Fowler, reef, aggressive or peaceful. That will make a difference with what kind of fish you will want. No matter what fish you get may I suggest a cleaner shrimp. We just g bought one and with in 5 min of being in the tank he was already cleaning my Naso Tang. The fish almost fight waiting in line to get to this shrimp, really neat to watch. Good luck with the tank, they are a blast.
