Hello all, I’m almost a year into the hobby I have a 90gal(4ft) setup. I’ve had a scopas tang since January without any issues. It was skinny when I purchased from the lfs but was starting to fatten up. I moved around some rock work (was only working on one side of the tank so did not remove my fish rookie mistake I know)to create more hiding places within the two months due to my scopas scratching its side when trying to go into the cave style rock I have. Following this it did not go under the cave rock anymore and found a new area under a large arch. I thought this would give more area for territory within my tank and all would be well. Following the move around everyone in my tank seemed to be doing alright (one clown, scoops tang, lawnmower blenny, opossum wrasse, long nose hawkish, and tomini tang plus a few hermit crabs). Within the following weeks my scopas tang (who was tank boss) started acting like it wasn’t feeling well, wasn’t ripping into nori like usual, mouth wasn’t chewing like normal to do the ripping motion, was still eating mysis, and other frozen being broadcast fed to the tank but not exhibiting the normal grazing behavior I knew him/her for. I realized when researching it could be HLLE from carbon, which I had added into my filter a few days prior. After removal two weeks ago, it still didn’t seem to improve also my other tang was not affected by this. None of my other fish are showing signs of stress to my knowledge. I’ve done the large water changes, but my scopas tang was still exhibiting stress colors being much more passive and not eating correctly. I noticed weight loss further, which was concerning yesterday I removed from display and put in a QT tank with general cure since it’s what I had on hand and had medication coming to treat for potential parasites or fungal. My tang unfortunately passed this evening. I have photographs which I will attach my biggest concern is everything else in my display tank at this point.
I’m not sure of a diagnosis given everyone else is OK but would like to catch it if possible so I can get the medication and treat the entire tank if needed. At this point, I’m not sure if my scope tang was hurt following rocks moving around maybe impacted it’s ability to eat and the lack of nutrition is why I started seeing HLLE and he basically starved to death over weeks, which would be extremely sad, or if it’s a carbon issue why it didn’t get better after removal and why he was getting so skinny or if it was potentially a parasite or something I visibly couldn’t see making him sick, which is in turn the reason I am on here that way I can prevent further loss. All other fish in my tank over the last few weeks haven’t given me any issues. I did lose a horseshoe crab who was newer but other than that I haven’t had any loss.
Everyone else in the tank also seems to be fattening up compared to when I got them so I don’t think it’s a lack of food issue my other tang although still a juvenile has gotten bigger as well as my clown fish my hawk fish has been okay no deterioration and my lawnmower blenny at full-size is also staying the same. (Opossum wrasse which is tiny was introduced after I noticed behavior with my scopas tang about a month ago and they seemed to get along just fine)
Just looking for guidance on if you think this is a injury, causing death incident or if there may be illnesses at play that I need to address any direction helps when looking at images I’m not finding anything online matching the black splotches that were on my tang, although I can note HLLE which could be from stress, but the skin coloration or scale coloration has me stumped.
Water color from general cure.
