Whitish wild X. helleri female.

[edgar zavala]

Hello everybody, I´ve bought some wild swordtails and one large female after tree days more or less folded its fins, none of the others, and instead of been translucent became whitish. So, Was this a reaction to some kind of intoxication and not a true disease? the rest of the fishes are doing well. Thank you.

Does the whiteness look like fungus?
