Hi all. Just came back from a few days trip to Grand Canyon and noticed my sailfin tang had these dark spots all over its body and fins. Not quite sure what it is but I’m worried it’s black ich.

water parameters
Nitrites: 0, Ammonium: 0, nitrates: ~60 (not great I know, working on fixing that), Temperature: ~74°F
Stocking: sailfin tang, powder brown tang, cleaner wrasse, 2x clarkii clowns, canary blenny, royal gramma, coral beauty and lemon peel angel, starry blenny, pink spot goby, some urchins, snails and hermits
Equipment: protein skimmer, blue media balls in sump, canister filter, ATO
Tank size: 180 gallons
Nuisance algae: cuando outbreak, trying to get it under control
Most recent change: adding the powder brown tang

any info would help. Also if it is black ich what’s the best treatment method? I don’t currently have a quarantine tank so I want To make sure this doesn’t turn into an outbreak and kill the tank

Hard to tell for certain. Looks fairly flush to the skin but like I said I’m not completely sure. Noticed that there might be a few on the powder brown as well but it’s also hard to tell as they’re nearly the same color as the tang. Cleaner wrasse is having a field day. If it is black inch, what’re my options for treatment?

Thinking I’ll go with the Prazipro option. Noticed that in the Humblefish post it mentioned that it’s reef safe so I was thinking I’d dose the tank in case there were any in the sand, rocks, or if any of the other fish were infected without my noticing. Would this be ok or would it be better to do a QT tank? I have a 10 gallon I could set up as a qt but I worry about confining the two tangs in that small of a tank (I’ve never done a qt tank due to space issues though I plan to get a qt setup when I move out). Appreciate the advice so far and any more to come too, thanks.

Sorry, I stepped away from paying attention to the discussion cause I thought it was getting better. Yesterday the powder brown died, got home today and now it seems like my whole tank is crashing. Starry blenny is dead, other tang is not looking like he’ll last long. One clown’s eyes are cloudy and she’s on the ground breathing heavy. The clown looks stressed but not in mortal danger. Only fish that seem unaffected are the cleaner wrasse, pink spot goby, and coral beauty angelfish. No sign of lemon peel angel. Urchins and hermits seem fine as well.

did water testing and ammonia spiked up to 0.5, I used some water detox/prime to try and help a little bit but I don’t really know what to do. I have an empty 75 gallon and 10 gallon. Don’t have a hospital tank/QT setup

How old is the tank setup, I see a bunch of sterile looking rock?
The tank has been on and off. Had to completely tear it down last year in may when we moved houses. Tank had been going for a few years before that. A lot of the rock is 10+ years but most is 5-10 years

How would you set up a hospital tank? As i mentioned earlier I have an empty 75 and 10 gallon tank but nothing in the ways of a dedicated hospital or QT tank.

Probably will set both up just so the fish aren’t all crammed into one tank. 75 will eventually be converted to a display tank. Just a bit set back by the crash. Saw some sites mentioned putting a bag of media or substrate in the tank but keep it contained. Think that would help or would it hurt given neither tanks have been used in at least a year?

After putting in some water treatment the ammonia is almost zero again. Have water in both tanks (realized the 10 is actually a 5 gallon). Aerating the water and letting the pumps run for a little while before putting any of the fish in. How long should I wait before trying to move any of the fish. And when I do, should I just move them over or do an acclimation cycle?
