I have 2 beautiful Golden Semilavartus Butterflyfish. They are new residents in a 300g FOWLR tank. They were quarantined for 3 weeks. The addition of them has been very peaceful. They swim and eat as a community with no issues. In fact they eat like crazy! My cleaner wrasse has welcomed them to its cleaning station without issue. A few days back I noticed a couple of white lesions on the pectoral fins of one of them. Now, as of today the fish has a white plaque-ish film on its body. Doesn't look like ich to me. The fish is acting normal, not like velvet where the fish will sit in front of the powerhead, etc.

Can someone reliably ID this and tell me how to treat? or do I need to treat? Is it fungal? Maybe a methylene blue dip? Please help. Much appreciated.

What did the quarantine process consist of?

If they are not breathing fast, it isn't velvet. Old ich infections can look like this, but when they first start up, you would see distinct spots, so I think you can rule that out.

I'd be leaning towards flukes at this point. I would skip the methylene blue dip, those are useless. However, that implies you might be able to catch these fish? If so, what about trying a 5 minute FW dip to see if flukes drop off?

I too think flukes as nodules are quite large to be ich or velvet However Im surprised none on the eyes as much as its covering body, and looks like Brook also but typical for this fish which is generally susceptible to bacterial and lympho issues

Qt was 2 weeks in copper one week no coppe plus carbon and skimmer.
I think I can catch them.
thanks.
any other recs?
Copper won’t deal with flukes. You could try the FW dip, or treat the whole tank with praziquantel. If you dip and find flukes, you’d need to treat with prazi as a follow up.

Agree with @Jay Hemdal How about the rest of the fish in the tank (Assuming they are not the only 2)
The rest of the fish are perfect. Nothing at all.

Emperator- transitioning
Lemonpeel
Queen angel- juvenile
Flame angel
Regal angel
Gem tang
Dejardini
Purple tang
Flame hawk
Longnose hawk
Royal gramma x2
A few pajama cardinals
6 line wrasse
Blue cleaner wrasse

is it possible the quarantine was ineffective?
Thanks for taking an interest here.

Ok. Easy catch. Fish literally went right into the trap while I was putting in the tank.

Dipped in RODI freshwater for 5 minutes. Temperature the same as display.

Did not see major flukes jumping into water. Maybe one or two could be flukes or residue from bucket, even though I cleaned it thoroughly. I don't know.

Images of catch and post dip.

Should the white patches go away immediately post dip?

Next steps please? Thank you. I feel very confident knowing the expertise involved in this case.

If it was Neobenedenia, you would have seen dozens of oval things in the bucket that looked like fish scales - pretty hard to miss, so I think we can rule that out. One thing though - did they posture for the cleaner wrasse a LOT? If so, they may have Neo, but the wrasse may have picked most of them off, leaving white areas of skin damage.

At this point, the differential diagnosis would be a bacterial skin disease. Treating that by a dip likely won't work. It may go away on its own, but if the spots have grown in size and number, that is probably not the direction this is going.

No easy solution for this I'm afraid.

Ok. Definitely did not see dozens of oval flukes. The fish does NOT posture for the cleaner very often. Similar to other fish. In your opinion, should I just wait it out or catch him again and treat with something else? Everything tools good and healthy in there. Never easy with fish disease for sure.

Here is what I would do: set up a medication tank with some operating bio media. Pick up some gram negative, broad spectrum antibiotic to have on hand. Then, watch the lesions. If they get worse, move the butterflies over and start treating them. If it resolves on its own, then you don't have to treat them.
