You know I haven't noticed any but as I take more and more macros of my acros.... (hehe), I have noticed these on a few colonies. I guess I need to figure out how to get rid of them. I can't see them with the naked eye but on a few pics I have noticed a couple.
LOVE the pics! especially love the fish pics, they enhance the personality and character of the fish, I think having close-ups of my fish would make them even more real, almost "human" as odd as that sounds.
i wish i could take close-ups like this! i really need a new camera.
