Thank you. Other fish don't seem to have any. The problem is that it was pretty much invisible without my lighting directly shining on her from overhead (I am not even sure if she has any now cuz she avoids areas with strong lighting). I couldn't even see them when I pointed my flashlight at her from the side. My CPDs are constantly moving around in their shiny tiny bodies, so I can't see any. I don't see any on my Honey Gourami but he is bright yellow. BUT, these two Gouramies have been flashing occasionally (maybe once a day against largest leaves I have during my presence but never repeatedly.)
