again, different creatures diffetrent needs, this means each coral has different needs form each other coral
as for he anemone, it is not a coral
they do need lots of lighting, but I would actually reccomend agaist them, they are not easy to keep for long. Infact, I reccomend against them even in most experienced hobbyists tanks. They are interesting andbeautiful, to say the least, but don't live long in most aquariums, adn they should live for decades and maybe even centuries.
And clowns do NOT need them to be hapy and healthy. Do not listen to an lfs about this most of them will sell you one anyways, even if they did know the facts.
Gor a 75 with your intentions, I would reccomend strip of 2 x 65 watt pcs(10, 000 kelvin) and 2 NO florescent lights with actinic bulbs, for most hings, except maybe clams which could need even more.
