Most LPS don't need feeding, but they do a lot better if you do. I have started feeding mine more regularly again, and they are looking better than ever. It is definitely tough to keep an SPS/LPS mixed reef. My tank was supposed to be LPS dominant with some deep water Acros up higher, but my LPS don't like my new tank as much as I was hoping they would (lights are too bright and they don't like the Wavebox), so it is quickly getting more and more SPS. Dangit.

To give you an idea for lighting, I have a very similar brain to yours, and mine is happy on the sand (24" deep tank) with my 250w DE halides (they are 20K, so not high PAR) right under the bulb. I have 3x 39w T5s that come on when the halides are off to make a 12 hours photoperiod, but they are not on at the same time as the halides. The brain would bleach out in my 33g tank merely with 2x39w T5s if I didn't have it off to the side of the tank where the light wasn't as bright and on the sand (16" deep tank).

My brain gets fed only rarely, but the colors improve quite a bit if I feed it just a couple mysis every week.
