When I started my just filled 65 gallon tank with live rock I use to sit in front with a magnifying glass and look for my first bug or any sign of life. Slowly watched the tank go through its cycle. Lucked out because there was this one small zoa that grew kind of fast and multipled. With no fish in the tank the bugs were king and then all kind of things appeared. In all honesty it was probably the best time I had with the tank...
