Definitely right with the patience part, I don't want to go too fast with stocking and not have room for cooler higher end critters due to lack of space. I can't afford high end fishy right now so I'm keeping stock low until the holidays. My uncle used to be an avid reefer so Christmas I will go for some new upgrades and livestock.You sound like you are off to a great start! I recommend patience. Go slow. After you upgrade to a larger tank size (maybe in a couple years), your 13.5 will be a great quarantine tank.
