bristle nose catfish...ick?

[robertoi]

Hi all,
I have quarantined 5 neon tetras because they are showing signs of ick, and Im treating with waterlife protozin as per instructions. In my main tank though, I now have a bristlenose catfish all on his lonesome. Can these fish develop ick? and if so, how should I treat - with the protozin at a reduced concentration or just with temperature increases???

Thanks
