There are several low light inverts that you can put in their. All feather dusters, bubbles if you put them up high, most any polyps, zoonatheds(sp), ask a reputable LFS but MOST not ALL soft corals don't require tons of light. Although the more light the better they will grow. Just stay away from stoney corals and anenomes. You are running 2.4 watts per gallon. They say you should have at least 3 wpg. I am running 3.6W and you can see what I have. good Luck!
