Fin rot on new fishfish

[jaws7777]

Hot this guy monday. Came in pretty bad shape allot of red streaks on the fins. Added salt and kept the water clean. The red streaks are gone but to me it looks like the fins are disintegrating more.

Taken the other day



Taken today.



Should i treat with meth blue ?

you could try MB but because it is advancing quickly, I thinnk it warrants an antibiotic. Looks to be a aeromona or similar(psuedomonas) infection, erythromycin is a good one for that. Is this fish still in quarantine or main tank?

 

[jaws7777]

Still in qt. If we went with erythromycin is there a need for MB ?

 

[Wailua Boy]

I would try one or the other

 

[jaws7777]

Searched amazon. Kanaplex and furan 2 came up.

 

[jaws7777]

This ?

 

[Wailua Boy]

My next choice would be triple sulpha, if erythromycin cant be found

 

[jaws7777]

Thx bro.
What is the difference between MB and the kanaplex/erythromycin type meds ?

 

[Wailua Boy]

MB isnt an antibiotic. I just figured since you already salted, ,may want to try something stronger. Granted polys are very strong fish and could well heal on its own but for most others species I would dose with an antibiotic at this point

 

[Wailua Boy]

If you have MB on hand you could dose with that immediately and watch for improvement
