Through work with alan I have been able to isolate this. All widebars, and almost only widebars above all other datnioides suffer from these when there is a drop in ph and water quality. When I first got my widebar off andy it used to get them regularly. They never seemed to affect him and he always still acted normal and continued eating but they would ooze pus and then once I'd do some water changes they would clear up. But they would come back after a few days. This happened for a good year. Not all the time but on at least a dozen occasions. Because they never affected his behaviour I literally just thought I had a teenager with acne for a fish!
In speaking to alan he suggested pretty much it was my fault and I needed to keep the fish in far better water quality, reduce the stocking heavily and up my changes. At first I didn't take it too seriously. I had 2 fx5's, a tetratec 1200, and 2 fluval 4 internals on a 7x2x2. I did a big change every weekend. I'd seen others with more stocking in similar size tanks. But the spots kept happening and alan kept on at me so I decided to test my ph daily to see the fluctuation. During a week my ph would go from 7.4 post water change to 6.4 exactly a week later. That was enough. Others have protested about "dat disease" but the simple fact is ph fluctuation imo. I cut my stocking by a good 2/3's as I couldn't manage extra water changes (I do 35-40% weekly) or a bigger home than the 7x2x2 he was in. I haven't had any sign of an abrasion for the last 18mths. The fish has never looked better. During a week my ph can now fluctuate from 7.2 post change down to 6.9 a week later. I'm firmly of the belief that thinbar sudden death syndrome is caused by the same. As these tigers grow imo they are more and more sensitive to water quality.
As alan always says to me, some will listen, some just don't want to listen, but what that guy doesn't know about water isn't worth knowing.
but one day i will get back into it
