Clown gobies with SPS?

[ToshAlexandra]

I previously had a lil green clown goby that I adored, but I only had two small pieces of SPS, a pavona and a bonsai, and he would perch on them all the time and would irritate them, ie the polyps wouldn't be out and generally appeared annoyed. I have about 10 pieces of SPS now and wondered if anyone else had kept them successfully with SPS without them being too much of a nuisance? I'm just in a 28g nano, so probably wouldn't be the same as a bigger SPS dominated tank, but just curious! Oh and also if anyone noticed a difference between the green clown goby and a yellow clown goby based on how they affected the SPS - Thanks!
