Not a recommended fish for a new/newer tank and has bacterial issue which has also affected the eyes. Not sure how youre testing but with a tank this new, while possible, I am not convinced on Zero ammonia and would encourage you to take a water sample to a store that does NOT use Api kits and have them test your ammonia and nitrates and compare readings- then you'll know where your levels truly are atCHOCOLATE TANG
2 weeks old new tank, notice today hanging out in the corner with head down. Swimmers up and down the glass, 150-gal tank salt 1.025, temp 77.4, PH 8.2, ORP 323, NH3 O, has been eating good until today.
There seems to be a fair bit of algae, etc on your tank wall - so that part seems 'ok'. Are there other symptoms - breathing fast, red gills (which can help suggest issues with ammonia) - are other fish also having issues (if not, it's likely not ammonia). I agree with @vetteguy53081 that at least in part there could be a bacterial issue. I would add copper to the antibiotic (in a hospital tank) - if you didn't treat it with copper up front. Usually I wouldn't recommend this - but the fish looks quite ill. If it survives, I would treat with the usual prazipro protocol. I would carefully monitor for any symptoms, issues with remaining fish - and CONSIDER - if they have not been properly quarantined - to do that as well. Hope this helps! Good luck with the tank
