Hey guys, I really need help with this one as I have never come across it before in all my years of fish keeping. I change 25% of the water twice a week and have tested the water and nothing seems out of the ordinary. The tank has been running for 3 years and I have not added any other fish in this time. One of my rainbows has a sore looking thing on its abdomen and under its chin plus a white fluffy looking fungus on its tail. Some of the other rainbows have the same fluffy stuff plus a few white speckles on their fins. I have tried pimafix and melafix over the last 3 weeks combined with water changes and still nothing has changed but only seems to have got worse :/ heeeellpp!!!

Sound like Flavobacterium Columnaris.

 

Methylene Blue would be my first response as it is a gram negative bacteria. Oxytetracyline may have some effect also.

 

Ciaran

But thanks anyway

Hello Eejay,

 

If you decide to try methylene blue as a treatment, I suggest that you do so in a bare tank, as this chemical is usually destuctive to living plants, and will also tend to knock out nitrifying bacteria in filtation systems, with subsequent  rise in ammonia/nitrite levels. Just do not feed any fishes in a bare tank for the duration of treatment with methylene blue.

 

If you have the wherewithall, I would like to see a photo of the affected fish.

 

Syd.

I had an issue with something similar with some natives. I used multi cure which is methalene blue, malachite green and something else... Cant remember but it cleared them up pretty quick. It made the water so dark i didnt see the fish for a week.
Good luck with it, chuck a photo up for best advice.
