The MH out put a much larger amount of light per watt than either T5's or PC's. Which is also why they get very warm.
Where abouts in your 29g (subliminal) is your anemone sitting? Probably right at the top, or near the top. T5's would be okay and much less cost, but I tend to prefer the different customization options that you can have with halides. (i.e. different K's, combo fixtures, a little easier to DIY.)
