Looks to be either Ich or Velvet. I have not experienced either so am not too helpful. @MalEficent recently successfully treated a purple tang with ich and may be able to help.

Quarantining affected fish can help reduce loss, but if this is actually ich, then it’s in the tank and the tank will need to be addressed. Safest option is QT > treat fish > thoroughly clean aquarium or replace it (then cycle new tank with nothing from old tank unless it has been thoroughly cleaned). It does seem like ich, but not easy to confirm with photos. Any inverts or coral? If Ich and no coral or inverts, then you can treat the main display. Will most likely need to replace rocks and sand (properly), once done with treatment. Treatments aren’t really “reef-safe” but I’ve had success with Copper Power (with proper sand and rock replacement after treatment) and then re-adding inverts (no coral) with zero issues or changes to their quality of life.

@MalEficent 1y

Oh no 😢 for your fishes sake I hope it’s ich. Ich can be deadly but can be treated/managed. Unfortunately, this looks more like velvet to me. Velvet covers the fish more than ich, spots are smaller, and it spreads extremely rapidly. Ich can take several weeks to show up on fish and considering your order fish are already showing signs it’s likely velvet. Velvet has a high mortality rate but can be treated. I suggest removing ALL fish into a quarantine tank as fast as possible and starting treatment. Then leave display fallow for 6 weeks.

@MalEficent 1y

As a follow up for treatment, the treatment is essentially the same for both ich and velvet. As @billy mentioned, I successfully treated a purple tang with an extreme case of ich. It’s a lot of work, especially with multiple fish but absolutely can be done. I used three tanks. One tank is set up as an observation tank. The other two tanks are used for a two week treatment. Start the fish in one tank and dose copper to a therapeutic level. Leave them there for two days then transfer the fish to the secondary tank with copper at a therapeutic level. Sterilize the first tank with vinegar or bleach. Let sit and completely dry. Switch tanks every two days at therapeutic copper levels. After two weeks transfer the fish to the third observation tank for two weeks. The treatment is essentially complete at this point you’re just making sure everything has resolved and treatment was successful for two weeks in observation before transferring to the main display. The two weeks for observation is for displays that haven’t been infected, in your case since your display is affected you would keep them in observation for 4 weeks for velvet or 9 weeks for ich to clear your display. There are in tank treatment options but they generally aren’t as effective for severe cases. The trick/expensive part about this method is you need to have three of EVERYTHING to not cross contaminate tanks. Three heaters, three wave makers or air stones, and three sets of fish hides/pvc. If you start treatment now your other fish will likely survive this method if they are fat and healthy before they got sick. This guy is hit or miss. Good luck!! You got this!

@MalEficent 1y

Sorry to be super extra in response 😂 but traditional treatment is therapeutic copper for 30 days. The problem with this is copper is toxic and takes a toll on fish and sometimes fish succumb to the treatment regardless of the illness. Even with the 2 weeks my tang came out with HLLE but she recovered pretty quickly from that with proper care. The two week method I got from humble fish if you need/want more explanation.

Thank you all for you responses! This morning I looked at all my fish, unfortunately I don’t think my tang will make it. I feed them this morning they all eat except the tang. He seems very lethargic, and can’t swim properly. It also seems like he has gotten smaller in size compared to when I got him, his stomach also seems to bulge. As for the puffer some of the white spots have fallen off, I got him along side the tang but he still seems healthy (aside from the white spots). I also don’t have any inverts or coral I just started this hobby at the beginning of the year! I also just recently introduced copepods and have been dosing the tank with Live Phyto Feast. Again that you all for the help!!

@KingjamesTank 1y

Quarantine yes, But ICK is in every tank unfortunately it’s the fishes immune system to be able to push through the sickness… quarantine and dosing copper yes but you need to feed them with a extra supplement for immune system … SELCON ! Works the best easy simple to use! I swear by it.. I also work at World Wide Corals, Orlando Fl! If anyone want to come by and talk and check us out! I’m off Monday/tuesdays

@MrJuancito 1y

James thank you for your feedback! WWC is the exact place I go for all my fish needs! All my fish in my current DT have been from WWC. I also use Selcon, yesterday I thought I would arrive home to one less fish but thankfully I did not! The scopas seems to be making a recovery, no more spots… But it does still have a cloudy coating on the body. The stomach isn’t bulging any more, started eating again. Same thing with the puffer the spots are not there anymore. I know all my fish have been in copper before I purchased them. I also don’t want to do any medication if it’s not necessary to avoid stressing the fish out. I really appreciate all of you and your amazing feed back! Thank you!!

Well if the spots have fallen off it's likely ich . Unfortunately you tank now has ich it will not just go away . The fish you have in the tank might be strong enough to fight it off , but and new fish added might contract ich and the cycle will continue.
