I've bought Silver Dollar today. It was in a lfs
in a tank with other healthy fish, but when I brought it home and released it in my tank, I noticed something resembling Ich. Immediatelly, I moved it to my former hospital tank that is temporarily hosted by small Banded Leporimus and started adding salt to the tank. Still, I'm not sure whether it is Ich or not because looking at pictures of Silver Dollars and its relatives in Axelrod's Mini-Atlas of Freshwater Aquarium Fishes I see that all they have small white dots on their bodies. These dots look like their natural coloration.
Would anyone who have had experience with Silver Dollars help me? Is it really possibly that this is not Ich, but just pattern? I hate to keep this fish with Banded Leporimus for several week that is required for treatment (BL constantly gives SD hard time), but I will not relocate SD to my main tank if I'm not 100% sure about absence of Ich.
