Help with Long Nosed Butterfly

[Coach v]

I picked up this little long nose butterfly fish on Tuesday. He looked good minus being a little skinny. He is an aggressive eater though and has eaten everything from live bbs, frozen, to pellets and flake.

As we were getting ready for a weekend away from the littles on Friday, I noticed the little nub on his dorsal fin. Get home today and he now has white spots.

He is in my

qt/observation tank with several black mollies. I have the following at hand:

Erythromycin
Prazipro
Methylene Blue
Nitrofuracin Green Powder

I can make it down the mountain to my favorite lfs on Tuesday. I would perfer to do medicated baths, but have 2 spare 10 gallon tanks ready for qt.

What is my best course of action?

Looks like it might be Lymphocystis. It is a viral disease and no medication will help, normally goes away on its own when their immune system recovers from the stress of shipping and being held in less than ideal conditions at supplier.

Just to clarify, I'm talking about the nub on the dorsal fin, the spots looks like white spot (Cryptocaryon) and there are a few options available to deal with it (tank transfer, copper, hyposalinity etc).

I am setup for httm as I used to use that method. I will look into crypocaryon

Agreed that the growth on the dorsal fin is either Lymphocystis or a broken fin ray (common when you catch these fish). The other smaller spots are the concern - some of the spots on the head are pretty large, but the small ones on the fins look like marine ich.

All new fish should be quarantined for ich and flukes. I prefer copper and praziquantel, but hyposalinity also works. I don't use TTM because is only treats for ich, and is pretty rough on new fish, bouncing them from tank to tank like that.

Here is a thread I started on hyposalinity:

Hyposalinity

Hyposalinity Jay Hemdal 2021 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

As tempting as it may be, avoid buying thin fish and if you feel you must, ask to see it eat and find out what its eating. Also view fish for any skin imperfections, heavy breathing and even how it coexists with other fish in the tank with it.
A thin fish may be one in need of food, or ill or based on method of capture which may be by use of chemicals which you dont want
