Today I noticed one of my yellow tail damsels had three white areas in a vertical line behind its left fin. Now from what I'v seen the the white spots are much to large to be ich, I think that maybe he was darting through some small cracks and maybe scratched his side (does that happed?) If it was ich it would not be a huge financial loss to me but I've grown attached to my scooter blenny and would not like to see him become infected. So any ideas? I'll try and get some pics as soon as I find some batteries for my camera.
