In my 75g, I added a nem first and a mated pair of Darwin clowns as this important to me, and I needed to make sure the nem stayed put.
Then slowly added some corals every two weeks or so and least agressive fish first, one at a time, took a year, last fish was the mandarin and the red scooter.
My DT now has 60 mixed corals, 5 fish, a fire shrimp, a skunk and a pep....
I resist tangs....it's tough....but They all get big fast, require algae, and are Ick prone...
