@melev No signs or trouble with the HLLE I've heard can be a problem with these captive bred tangs? Just curious
What was described in one article felt like a disservice to the fact they were successfully captive bred. A proper diet can help most fish improve in health and appearance. I never blinked at the minor issues, they were not unexpected. Whether it was HLLE or thinning of the flesh around the eyes, I think in time they will improve. I've had them about a month or so now.
Typically HLLE runs along the lateral line, and these fish don't have any issues there. I'll try to get some better pictures to show the fish more clearly, and also document their progress (or lack thereof).
