I just started a new 46 gallon bow front. How long should I wait before I add some cycle fish? I was thinking zebras, but how many do I need?

You can start cycling right away, but I would urge you to consider fishless cycling as described in this article. You might also find this article on how to jump start a tank useful.

Imo adding pure ammonia is much better becuase it allows you to add higher amounts of ammonia and is controlable. Also more humane instead of subjecting fish to near poisonous water. The Ace hardware brand is good and easy to find. Contains 10% ammonium hydroxide or somthin like that.
