Columnaris or something else?

**ngrubich** · 05-19-2013, 11:11 PM

I just lost an angel over night out of the blue and wanted to see what everyone thought had happened. Its fins were perfectly normal and it was eating yesterday, but somehow over night the angel's tail fin eroded and its dorsal fin shows some erosion/dissection as well. My water parameters are in check, reading 0 - 0 - <5ppm: I did a water change 3 days ago just as a weekly maintenance routine.
I also lost two harlequin rasboras earlier last week, but they didn't have any visible sings of illness. The other 3 angels in the tank are hiding behind the driftwood somewhat, but will come out when food is introduced; the rasboras are swimming around like nothing is going on.

The tank is a 90 gallon setup with ~20 rasboras and 3 angels.

Sounds like Columnaris. I had it kill my sorority of 10 betta females one by one in a weeks time

Do you know of an effective treatment? I have been finding mixed reviews on how to exactly treat this.

I can't tell you how to treat it.

I am sorry.

There is no effective treatment. The best you can try is strong antibiotics and soften the water as in RO or distilled water. The bacteria doesn't do well with that combo.

does it matter which antibiotic I get? i.e. kana, metro, etc?

**ngrubich** · 05-20-2013, 02:32 AM

Also, should I treat the whole tank since I have no idea who all may be infected? From what I have read, it is highly contagious, so treating the main tank may be better?
