Welcome aboard! Sounds like a nice tank..
Danios might become fin nippers if you don't get them out after the cycle. To cycle the tank, you might just want to get a few of the fish you plan to keep long term, then give it six or eight weeks before adding more, and add more slowly. Using Cycle is a good idea, that will seed things and help it along. But you will need fish as well, of course, to cycle the tank. Put the bottle of Cycle in the fridge after you open it.
Hope to hear how it comes along and see some pics!
