Hello all. I bought a DF puffer a couple days ago and today I noticed these white spots in patches around his body. I don't know if they came on the fish but it doesn't seem to bother him. He eats and swims like any other healthy fish. They look too regularly spaced out to be ick, but I never had a scaleless fish before so I wouldn't know what ick would look like. Hopefully it's nothing serious. Thanks in advance for your help.
