I'm Also somewhat new and in my first month I have 3 fish, 5 corals, and a full clean up crew. I have a 12 gal started with 18lbs of live rock and 12lbs of live sand. I used AIP quick start and my tank was ready in 2 weeks. I have coraline growing crazy and my algae started getting out of hand. Start with really hardy fish like clowns, gobys, damsels. And as far as corals start with softies like gsp, zoas, shrooms, xenias. Don't get the black clowns, they get to big. And think about your cuc asap. Algae will grow quick especially if you are seeing coraline. Just my experiences. Also the cleaner shrimp is great. * I started my reef on 5/6 I will post some pics for you.
