New Project 
I'm setting up a 10 gallon tank hoping to put a pistol shrimp and a shrimp goby, and maybe a few other nano fish.
Question 1:
The problem is that the hood's light is only 18W, I'd rather not change out the lights and do another DIY lights project so I was wondering what corals if any could I keep?
Question 2:
I'm thinking to sticking to non-photosynthetic corals, but what other corals besides sun polyps, chili coral, and gorgonia are non-photosynthetic?
Thanks for the help
