This is my build farely new of course but so far so good but Im missing a whole lot of color so far I have two duncan corals that are growing like wild fire and BTA anenome that decided to hide under a rock and some kenya trees that are doing good. What would you guys suggest I could add that would color up the place not to mention liven it up.

 

Way too much to name, I would reccomend looking at zoas first, and then acans. They both come in pretty much any color you can think of.

 

Ya think I got to much rock going on in there Im thinking of removing the top layer of rock.

 

I don't think you have to much rock at all. Looks good! Personally I'd get rid of the Kenya-can become troublesome as in invasive. But that's just me.
Mentally section out your tank. High-medium-low. Research the corals your thinking of and choose according to lighting requirements. Most LPS prefer low-med light. SPS High light and most softies prefer low-med light. Then work your flow around them. Most sps like high flow-LPS low to med same for softies. This way makes it easier to choose your corals
