So I was by my buddies house checking out his set up. I noticed MICRO white worms wiggling on the surface or the water and then I noticed some tiny white flies. It seems the are reproducing on the surface of the tank? Has anyone ever seen this b4? I tried to take a pic but they are too small for cell phone to focus on. How do you get rid of something like that? His Rays are FAT and suppa healthy - he only feeds what they will eat and tank looks clean. Says he services filters often? I just dont know - never saw this B4 myself. What do u guys think?
