You should beable to keep anything you want under that lighting. I had 8 T5's on my 150, and they were nova's, I understand they are not as good as the tex, so you should be fine with the 6 tex bulbs. I have a clam, anenome and some sps. I did replace 4 of the lights with MH because the fixture broke, and I had a MH fixture in storage, so thats what i am using now.
