I have a 20 long with only 2 clownfish (live rocks, live sand)

would you consider using this LED light? What kind of corals would be ok for starter corals using this light and by any chance any of those corals would host my clownfish.

At 0.1w per LED, the output is only ~8w. Nowhere near enough light for photosynthetic corals. For a 20L, a used T5HO hood (or retro) would be a good value option.

If you want to go LED, check out the Nano forums for recommendations. A 30" fixture from BuildMyLED would let you grow anything. Alternatively, 2xPAR38 bulbs with wider optics (RapidLED offers 80°) would provide the good coverage.

+1 with the OP, not at all...

What corals are you trying to grow?

For LED I would go with these: http://www.rapidled.com/solderless/

I'm not sure what corals to grow. I just started the tank and my live rocks came with feather duster, ball anemone and a sponge. So far they seem like they are doing fine. What can I grow (start with) with this light.

It 1 watt per LED not .1 sorry

You are going to need much better, high intenstity lighting for most corals. Lighting is one of the greatest costs in this hobby.
