It has been identified that the skin rash is not itch. Unfortunately, the fish died this morning. I will provide photos later tonight.
I think another problem on my part is when I bought the fish, it was in a tank with other thinbars that had the same time of skin rash but being the excited thinbar addict that I have become, I still decided to buy it. Don't get e wrong, the seller was a definitely cool guy.
I bought two thinbars and both of them died on me. The one in the photo above had wonderful colors... too bad it died.
I think I might refrain from getting any dats at the moment. I will probably wait until my dats grow to around 4 inches or more. The thinbars are so sensitive compared to indos, NGTs, and silvers. I will most likely get thinbars in the future that are 4-5 inches in length...
