I have 3 banded rainbowfish (1 male, 2 females) in my filtered/heated 60L tank. The tank also has quite a few live plants and plenty of swimming space. I've had them for nearly 2 weeks now and about 3 days after I got them i noticed that all 3 of them had small white tuffty-looking growths on thier mouths.
The fish were in good shape when I bought them and there were no sick fish in the shop tank. My tank was well matured (I kept some tetras in there for 8 months - which I have now moved to a bigger tank - and I never had any problems with) and I did a 20% water change and gravel vac after I noticed the growths and treated them with "Aquamater Fungus Cure" and repeated the treatment after 3 days (as it says to on the bottle) I also added 3 tablespoons of aquarium salt (as recommended by my lfs where I bought the fish along with the fungus meds) to the tank.
Its now been nearly a week since I started the treatment and the growths are still there. They haven't spread or changed size either and the fish are still eating like normal and swimming around, sometimes they shake their heads a bit (trying to get rid of the things on thier mouths?) but other than that thier behaviour is normal.
Just want to know why the treatment didn't work and if it was something else (not fungus as I treated for), why didn't the growths get any bigger.
Heres a picture of my boy - you can kinda see the white in the photo. Pictures by rainbowfishies1 - Photobucket
heres a link to a few more photos.
I'm just worried about what it could be if the fungus meds didn't work and that it might spread to thier fins/bodies or something.
Any help appreciated
