wondering thoughts of others, with more experience. i got a coral from another reefer, his tank looks amazing. i dipped it in bug out, and seachem reef dip. some weird flat worms came off in the transport bag on their own. (i posted to hitchhiker forum). nothing came out in the dip process though. 2 days after i added the coral i see my yellow tang flashing. never saw him do that prior. none of the other fish showed flashing (clowns,gobies,cardinals). then i started seeing red on the tang. first blotches, then concetrated redness on fin bases and back area. reading threads i saw comments about biota tangs doing this after a few months and it going away. but this wasn't going away, so went back to thinking about the flashing, and it breathing fast, and the coral addition. i dosed with prazi. and he seemed to show improvment in the red within 24 hours. i managed to take this photo after treatment. and i think those look like flukes turning white. wondering if you agree, and i didnt' know flukes would come in on a coral. i had watched a reef rookie video saying the comin in on fish.

Unfortunately, the issue with 1 fish means all of your fish should be treated. I personally do not believe the dips do anything to prevent fish related disease - but are instead designed to prevent coral related disease - which is why many people quarantine their coral in a fish-less tank for 72 hours (Edit - days)

In any case, how big is your tang? Small tangs can be difficult - and it may be a bacterial infection, it may be a parasitic infection, and it may be something else specific to that tang. Usually red coloring like this Is more of a bacterial infection - like sepsis. I would remove the fish to a hospital tank and treat with a broad spectrum antibiotic. At this point, if your other fish don't have symptoms, I would leave them - and you can also treat the main tank with prazipro.

For the tang - in addition to the antibiotic, I would give prazipro - in a hospital tank setting. I'm sure others will weigh in. Hope your fish will do well

Neobenedenia fluke eggs have sticky tendrils and move from tank to tank on corals, etc. Dips that won’t kill corals also won’t kill these eggs. However, the person’s tank where the corals came from would be showing some evidence of having flukes….

I don’t see definitive symptoms of flukes on the tang - it has something, but the visual symptoms don’t line up with flukes.

Seeing so many yellow tangs in captivity, ive seen this many times and often associated with vitamin deficiencies often with wrong foods or insufficient diets offered to these fish. Another sign of deficiency is lateral line issue seen. Other would be gram positive infection often stared with stressors in environment
What foods are you offering fish which is slightly thin?
 
it has, well...was gaining color and weight, from when i bought it. i offer nori everyday that i soaked in vitamin. then ocean flake, LRS reef frenzy, mysis, sprirula brine, forumula 1, 2 and prime all on rotation. after the prazi treament it did a good bit of twitching and spasmsing, and i probably was seeing things, or wishing too, but the red let up. been a few days now and its mostly gone, though he's breathing SUPER hard and lost appetite. which i (again another theory) think might be related to the dinos. my snails are dying and i'm losing corals. i have another thread where i posted video from microscope looking for help on that.

i thought maybe i caught a photo of the flukes here on the tail area, i tried to zoom in more for you. i've never seen them IRL. maybe that is just roughed up skin from him flashing.

was small, like 2" when i bought it i guess 6 weeks ago now. was basically see through too. i've not seen any nice tangs for sale. shop told me that is how they all are now from biota

Those look like mucus plugs or bacterial tufts. Most fluke species are too small to be seen with the naked eye. I’ve sometimes been able to see Neobenedenia flukes on a fish if the lighting is just right - but those are larger and distinctly oval.

okay, well i couldn't see it by eye, i saw when i zoomed in on a photo i snapped. actually noticed this pic later, not when i took it. it does seem odd that there'd be a cluster of flukes all together like that, but again, i've never seen them by eye. i was going to try to trap and FW dip, but he did not go anywhere near the trap when i was trapping out the cardinal, even after days of it in there. and i didn't want to stress it out more.
 
I[m still going to say the red streaking - though sometimes seen on tangs - represents a bacterial infection - I would check with Biota if they see this pattern normally

understood. he is looking better now. IDK if prazi was the thing or not. i also think maybe it could be tied to the toxic dino issue i apparently have.
