Nuvo 16-gallon Nano Reef

Finally got my first tank; a Nuvo 16-gallon Nano Reef. A lot to learn yet, but the internet, and sites like this, are a huge resource. About 19 lbs. live rock, not sure exactly how much live sand, but plain to see, it's a lot. Inhabitants include a Platinum Clown, Royal Gramma, Pinkbar Goby, Pistol Shrimp (not sure what species), and Red Fire Shrimp. Corals are a Torch, a Duncan, and a Branching Green Hammer. Also have 2 red-legged hermit crabs, and a snail (not sure what kind). I also seem to have a thriving population of pods, though I'm not sure how they got there-I never added them. The Clown and Gramma feast on them, the Gramma being a particularly agile hunter-love watching him in action. I might add a couple of more corals (a mushroom, or maybe a small polyp colony), but wouldn't think of adding more fish-seems just a right fit for the 3. Wish I had room for a bigger tank or for more tanks, but I'm grateful to have found one that fits my space and that I'm really enjoying.
