YCG killing candy cane?

[nanoreefer]

i have had a candy cane coral in my 2g pico for a couple weeks and it seems that most of the heads still are closed up/withered exept for one thats back behind the rest, ive turned down the flow and my water seems fine but my yellow clown goby keeps sitting on the coral and i was wondering if thats why its acting this way? and if it is the goby dos anyone know how i can get him out without ripping apart the rocks?

thanks!
