Fluval 6 nano
 

I just set up a Fluval 6 nano tank for my office. I am just going to put a mantis in there and about 8 pounds of live rock. I was wondering if there would be any corals I could put in there to finish it off. The standard lighting is two 10 watt halogens and they are centered so the corals would of course go right below.

Also I have heard of direct replacement leds for halogen light fixtures. Would those be a good bet and if so where can you get them?
