weird spots on cardinal tetra

[SilveRx]

Only notice 1 of the cardinal tetra having some weird spots on the body. 

 

can someone guess what this is?

First, when did you get the cardinal tetra?

Next quarantine it and treat it with melafix.

The photo is kind of blurry but it looks like some sort of fungus. Can you add another photo?

All the cardinal been in there for 2 months already and no new fish added within 3 weeks.

They move so quick, I'll try.

Dermosporidia/Dermocystidium, not really a lot of information about it or known treatments.

it does look like a small worm instead of spot, so should I take it out? or leave as it?

I'm having the same issue

I'm having the same issue with my cardinal tetras--a weird assortment of bubbles that have a wormlike white squiggle in them. Seems like a cyst-forming parasite. I'm planning to treat mine with anti-parasite meds to see if it has any effect.

I’m not sure if you guys were able to find a solution to this. I have 6 cardinals and one appears to be affected by this. @Frogmouth Catfish @silveRx

An article I read seemed to reinterate that there is no known cure, because it is a weird species of protist/fungi of some variety. They only recommended letting the tank 'fallow' with none of the affected species for at least several weeks before adding other fish of the same affected species back--it ended up killing most of my cardinal tetras over time. I could add more, but I've considered the tank essentially 'scuttled' for other cardinals--it doesn't seem to affect anything aside from cardinals, neons, and a few other closely related species, so the tank is basically fine otherwise.
