I’ve learned from mostly experience, if something isn’t happy then you should move it higher or lower and see how it reacts to the new spot. Honestly though if your light is good enough coral should be happy anywhere you place them. Highly recommend staying away from sps as they are very sensitive to change. Anemones are awesome and sometimes pretty hardy, don’t touch them much and let them move to a spot they like. The only other consideration I would think about is if the corals are close enough to start stinging each other.

Really depends on the person. Someone with less experience would do significantly more research than one who has been keeping corals for decades. If you're planning on keeping corals or any fish for that matter, I wouldn't concern yourself with thinking how detail-oriented you need to be, but how much you are willing to put your mind into keeping an animal. Generally, corals are known to be hard to keep, and even then, different types of corals have varying difficulty. However, it's far better to be overprepared rather than underprepared and you will always grow with more experience :)

@Craig Alexander followed by the rest of the fish, and anything else he puts in there..

was thinking the same, as well as the coral!!!

With the large water volume and small amount of corals, IMO I would say dosing is not needed on this tank.

YES! flame angels are gorgeous
