Well -
I'll reply to your post to get it on track.
I have 440 watt VHO over my 55 gallon in my office.
You could keep softies, most if not all LPS - You could do some SPS and people do with success.... I personally would leave SPS to MH Lightning.
With the tank being 75gal, keep in mind about coral warfare when deciding what to put into your tank.
I keep in my tank a few Zoos, 3 Finger Leathers, 4 nice size Ricordia Rocks, some Blastos, Acans - 2 Frogspawns, and a Torch -
I've also got some Xenia colonies along with Green Star Polyps and Green Center Stars
My 2 B/W Percs host my Torch coral. I prefer this over an anemone. I have personally tried an anemone in the past despite the many posts that say leave them in the ocean.
My opinion on keeping an anemone would be to leave them in the Ocean - There are other means of corals (Frogspawns, Torches, Hammers to name a few) that can give you the appearance of an anemone and allow your clowns a nice place to host.
If despite opinions on an anemone, should you decide to get one, I would recommend getting a clone from a fellow reefer with similar lightning if possible. This will greatly increase its chances of survival.
I've seen a couple softie tanks which were dominated by Ricoridia/Yumas/Zooanthids with a few Lobos..... _Very awesome_ tanks.... There is alot of color (I feel more so then SPS dominated tanks) and its fairly inexpense and easy to maintain.
Happy Holidays.
