Fins disintergrating

[rosepeddler]

I am at a loss. Water quality spot on, temp 78, excellent filtration, two air stones, calcium, salt,weekly water changes,etc. In the past two and a half weeks I have lost 8 guppies from my 29 gal tank. I treated once with melafix and lost 3 of the 8. My fry is unaffected. One Cory lost part of his dorsal and tail but growing back and doing well. Lost some beautiful fish. It does look like a fungal issue. The fins look as if they disintegrate.  Any suggestions.

Correction: It does not look fungal.

Sorry to hear....

Can you upload a few photos?

It is sometimes hard to pinpoint where this sort issue finds its root cause. My usual issue, personally, is over feeding.

I do use API products. Once you can pinpoint the cause... maybe API Fin & Body might help. If it’s fungus, perhaps API Fungus Cure. But you want to be sure. Maricyn might treat external rot...

What are your water parameters

[rosepeddler]

We images. Not the same fish. Not the pectoral fins are gone.

I would do a 50% water change  treat with maracyn or kanaplex it looks to bacterial infection

[rosepeddler]

I did a 33% water change last night. Can I use melafix or get maracyn?

Maracyn 2 better?

[Colu]

You can use  maracyn or maracyn2 maracyn treats gram positive bacterial infections and maracyn2 treats gram negative bacterial infection

Thank you. Adding it now as I type lost another last night. Hoping I can save the few left.

As mentioned above, what are your water parameters? Perhaps something will stick out.
