This is scary...your tank has been up for 2 months...you had this fish for 2 weeks, that means the tank was only up for 6 weeks, and you have "other" fish in the tank?I have had the fish for about 2 weeks, but he hid alot, when he did come out I noticed he had about 3 white spots on him. Not very big, barely noticeable, but at the time, he was rubbing himself on rocks, and I thought maybe he got something on him. Plus my coral banded shrimp poked him a few times, so I just assumed it was the scars, but I read up on ich and those were both signs of it, spots and rubbing on rocks. The tank itself has been up about 2 months.
How big is the tank? I think you are putting way too much in WAY too soon. Your water is not mature yet to handle what's being added. You water may test right, but that's not what I mean. Mature enough to handle the bio load...some help me here....LOL I know what I want to say, but it's not coming out clearAll my other fish seem fine.
