Yellow clown goby SPS polyp muncher?

[bigevill1]

I have seen my yellow clown goby nipping at two recently added SPS frags. Both frags have stopped extending thier polyps at all. Is the clown eating the polyps or picking bits of food off it. If it is eating I am in big trouble as this half inch fish will never get caught out of my 210 gallon reef.

I have a Yellow Clown Goby in 28 gallon tank and he seems to always eat algae or food off the green slimer I have in there. The green slimer used to look great with polyps out, now they are never out but the slimer is still growing like a weed. So I guess he is not hurting the coral just making it mad.

I told my wife if it doesnt stop I am going to go out and buy a lion fish.......

They do that to kill off the bottom polyps to make a nesting site for their eggs. In the wild, this causes the coral to die at the base but keep growing at the top so a protective "cage" is formed where they can make their home. It's not a problem on a natural reef, but not so good in the confines of a tank with small frags.

so lion fish it is!

I had one in my 50 gal that killed a couple small colonies of sps before I could catch him. I'll never get one again!
