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.

Fish was very thin and often hard to tell causes when deceased but could be internal.
Any recent signs of elevated breathing? HLLE which is light was likely not the issue
 
Thank you for letting me know! I was checking around every five minutes so it hadn’t been gone very long at that point. I appreciate you taking the time to read all of that.

Breathing was a bit rapid in general but this morning it got worse.

The timing, scratches and some fish not being affected all point to flukes being a possibility.

Curious about the water color - it looks sort of orange? General Cure shouldn’t change the color of the water…..

Hmm I’m not sure then I set up a qt tank using water from my main tank, I’ve used the tank before it’s a water box aio 10.5 gal. It didn’t have color changing until I used api general cure, bio bandage, and a bit of ammo guard, so I assumed it was that. How would I go about treating flukes in my larger tank effectively (want to make sure nobody else is impacted but I’m also relatively new to the hobby and don’t know best practices yet).

My other tang and all other fish are showing no new or alarming behavior and seem to be good. Although I would want to do any prevention possible if it’s something that once I notice it’s too late kind of situation.

I can’t tell if the water is orange, or if the plastic plants are just making it look like it is. If it is actually tinted orange, there must have been some reaction between the three chemicals that you added.

You can use General Cure to treat for flukes in your main tank as long as it doesn’t have corals or other invertebrates in it. If it does, you’ll need to dose plain praziquantel:
