how long to wait b4 fish?

[Finaddict]

Just wondering how long I should wait to add fish..

added 2/3 water from a cycled tank. 46lbs cycled rock, new sand mixed with 3cups live sand.
has 2 snails.
do i just check for an ammonia spike. or is it be cyclyed already?

tank is a 26g seamless bowfront.

was going to be a fututre home for a fuzzy lion or a fu manchu lion but from research they are hard to get to eat frozen foods...so
