White Patch And Loss Of Use Of Pectoral Fin

[cossie0]

Hi

I bought some rainbow fish a week ago (not sure which type but they are long thin fish silver with what looks like dark brown rust and red rest colours)

Soon after I noticed some of the other fish flicking especially my catfish so I thought I had an outbreak of itch. I increased the temperature to 82 degrees over a couple of days and started to use Waterlife Protozin

After a couple of days I noticed one of the rainbow fish was not swimming with the others and had lost the use of one of its pectoral fin. There was a white patch on its body around where the white patch attaches to its body. The next day I found it dead. Now I am beginning to lose other fish. I have lost a speckled baloon molly, a platy and a female figher The latest to get it is a big male sailfin molly who has the same symptoms as the rainbow and has lost the use of his pectoral fin. He also has flaking skin on his back, a white patch on the top edge of his dorsal fin. I have placed him in a small holding tank and he does not look happy but seems to be eating okay.

I am not sure what is going on but if I misdiagnosed and it is fungus then I would have thought the Protozin would be able to treat it as well (which is what it states on the side of the bottle)

My tank is a Juwel rio 300 (300 litres)
Amonia 0
Nitrite 0 (although this did go up to 0.1 for a day or so after introducing the fish)
Nitrate around 30
PH 7.8
GH 21
KH 5

thanks for any help you can give

Saddle back columnaris goes along the back and down the sides of the fish to look like a saddle that where it gets it name from.
The white pattches are they fluffy looking, they can flick and rub with columnaris which is bacterial.

Yes it is fluffy and seems to be eating away at the pectoral fin as well although this does not seem to be fin rot. The patches are fluffy looking and reading the description it looks like columnaris and I accelerated the disease by increasing the temperature.

I am off to the lfs to buy some of the meds it suggests if I can after a bit of further research

Thanks very much for your help

Get the temp down slowly as you are right columnaris thrives in high temps.
If you live in the uk waterlife myxazin, and pimafix.
United States maracyn one and two.
You will need to turn aeration up with adding the meds.
Don't forget to remove black carbon from the filter if you use it.
Can't add salt with having the cat fish.

Also affects the fins read here under columnaris [URL="http/www.fish-disease.net/diseases.htm"]http/www.fish-disease.net/diseases.htm[/URL]

I am in the UK

Will either (or both) of these two meds (waterlife myxazin, and pimafix) kill my filter cultures as well?

thanks

They shouldn't knock the benefical bacteria in your filters, but sometimes they do but only abit.

Hi sorry for the persitant questions

Would Interpet no 9 Anti Internal bacteria work? It claims on the side to cure diseases with symptoms such as bacterial gillrot, dropsy, ulcers and septicaemia.
This is pretty much the same of what it says for Waterlife Myxazin on a description I have just read.

I have a bottle of the Interpet stuff handy but want to make sure that I am giving them the right medicines.


thanks
Darren

I dont think much of the Interpet set of meds at all. They are pretty weak and i have never had any success with them. The Anti Bac med i ran recently at double dose - may have helped my plec out - but other than that i would go with the Myaxin stuff instead

 

[WILDER]

You can use the anti internal bacteria med instead of the myxazin.
To be honest I have never had much luck with the bacterial med by interpet either, the problem with uk meds is that you have to catch desease early for them to work as there not very strong.
