So the dreaded new fish always seems to have something after QT...just need to decide what it is. ATTEMPTING to get pics but he’s afraid of the camera when lights are off on the tank. Trying to determine ich, lymphocytes or something else. Of course it’s in my DT now...I got my QT up and running again when I noticed small white bump type specs on the yellow tang but need to know what it looks like so I can treat appropriately. No other fish CURRENTLY have the same thing happening to them. It doesn’t look like a blotch more of a white pustule some less noticeable than others but the ones I can clearly pick out you can see are raised when he’s turning around and you get the right angle. As soon as I can get clear pics I will also post them. If it’s ich I have to get another tank as I don’t want to treat for 30 consecutive due to the size of the fish I have and only a 20 gallon qt. My yellow tang being the largest is about the size of a donut lol. Have 5 other fish that I’ve fought hard to keep healthy to run into another sickly issue ugh! Thanks in advance!
