Our baby tomini has discolored white spot on him. It's not ich. It's not raised. Just almost like white patches. He's in QT with two long fin clowns. QT is currently copper dosed due to seeing spots on the clowns when added to DT. They were removed less than 20 minutes later. Spots on clowns where ONLY seen under the LEDs of the DT. You can't see them in the QT tank. So, what is this? They are feed pellets and nori sheet (for tang)
