Very new to the hobby, bought an established fish only 110 gallon tank and are converting it to a reef aquarium, slowly adding critters. Current residents- corals: a torch , a flowerpot, a rock of purple mushrooms, a green brain, a hammer, and a Xenia (I think). Inverts: 2 longspine black urchins, an orange and a burgundy starfish (linkia?) , a green brittlestar, a handful of cleaner shrimp and fire shrimp, lots of snails and hermits. Fish: Royal Gramma, a mated pair of Clownfish, a pair of Yellow Tangs, and a Goby.
