Can you believe that some people go as far as only checking the board only once a day? I know! Weird! But that's how they are. Kids and lives and television and dinners and actually doing stuff with the tanks sometimes takes people away from the 'pooters.
(In other words ... maybe in the future give it more than an hour or two before "bumping"...)
Anyhow, what can I tell you? I don't want to come down too hard on you, but you've asked some incredibly basic questions that a rudimentary search should yield you. I feel like a broken record but here we go:
They get large. You cannot underestimate how incredibly large they can get. They put a large bioload of a system. They will sting neighbouring corals. They can wipe out your tank if distressed (and I mean, wipe it out) if not happy (and it's VERY difficult to keep them happy long term). They have a horrendous survival rate in captivity and that alone should dissuade most sane people. They require a tremendous amount of current, surging current is best. They will inhabit the top part of the reef. If you put them on the bottom of the tank, they will not stay there -- if they can sense a path upwards -- up they will go. If they don't -- it's a bad sign. They want to be at TOP of the reef, where the currents and lighting are the strongest. If they can feel the glass -- guess what -- that's just another reef wall to them and up they go.
They can inhabit parts of the reef that are in water shallow enough such that they can be exposed to air during extreme low tides. This should give you a sense of the lighting and the wave action that they crave.
As such, you have to carefully design a system around this anemone. The tank has to exist for the anemone alone -- nothing else. I don't know how I can underline this point any more than this. To do this right they need to be the main focus of the tank, and you have to be prepared for the consequences if you try to make the tank too many other things. It has to be a very carefully measured choice.
