Whoa...slow down there. There are a couple of problems with your plan, and it would be helpful if you could tell us something about the remainder of your system (sump? skimmer?, how much live rock?j etc.). A 92 gallon tank is kind of borderline for tangs, who like lots of open water to swim in. Mixing tangs can also be a problem. So you have two problems adding to each other - the relatively small tank and two different tangs. Under crowded conditions the yellow tang may decide to defend its limited territory from the other tang, and the result is fighting, stress and an generally unhappy fishkeeper. Flame angel is a great fish for that tank, but be sure it has lots of rock to graze on. Flame angels are members of the dwarf angel family, as is the coral beauty. Mixing them together is also risky. If there are lots of rocky hiding places it could work, but no guarantees. You could probably maintain a mandarin in a 92 gallon system, but not until the tank has matured for a year. Most mandies eat only copepods, which require a mature tank in order to thrive. If the pods don't thrive, the mandy starves to death, which is the fate of most of these gorgeous fish. There are many threads on this site about mandarin dragonettes, and how to feed them. Suffice it to say that it isn't for the faint-hearted. Gobies - great. You will need more invertebrates than a couple of shrimp and a star fish. Take a look at clean-up crews (abbreviated CUC) on this site to get an idea of what you will need. Also, look at wrasses - they are spectacularly beautiful, many are peaceful and most can be mixed (I currently have a red velvet fairy wrasse, a seagrass wrasse and a yellow wrasse in my system, and they get along perfectly). Keep asking question and we will help you to refine your equipment and stock list.
