How long do you have to leave fish tank on?
The longer the better. If you used live sand and live rock in the setup it helps cycle the tank faster and better. There are also live bacteria products one can purchase and pour into the tank to speed things along. The first fish I always recommend are damsels since they are readily available, pretty, and inexpensive. I would wait a week, add the damsels, then wait another week, get your water tested at either your local petstore or if you have a testing kit yourself then if all checks out and the damsels are doing ok start looking for your first permanent fish occupient. most petstores will take back the healthy damsels, and some will give you a little store credit for them.
