Hello all, im new here, and new to the hobby. I work at a well known pet store in my area as an aquarium maintenance tech, thus it was only natural I get into the hobby. Anyway. Today I cam home and my clownfish have black ich. Maybe 20 spots of black on each. My royal gramma had some black smudges on his head for 2 days a few weeks ago, they went away, so I kept on keepin on. I unfortunately don't have a qt tank at home, I always use the qt room at work. The shop is closed for thanksgiving so I can't get my fish to into qt until Friday. I am wondering if they will be ok until then, and if there is anything I can do in the meantime to prevent things from getting worse. If it wasn't 2 am if call a co worker, but I have been reading posts from here for a while so I figured this is as good a time as any to register. Anyway, thx for any suggestions you all have, cheers.
