Our Oranda developed sort of red streaks in her tail that lead to what looked like a small White blister. This blister then seemed to burst and looked red and sore and the bit of her fin it was on looked a bit raggedy. I did 2 large 50% water changes one day after the other, then 2 25% water changes the 2 following days. The nitrate is down to around 10. I've also been adding aquarium salt but am not sure if I do this after every wAter change bearing in mind I'm doing loads at the moment. She looks happier and I THINK the fin looks less inflamed and the streaks not as red. Anything else I can do? Thanks!
It sounds like it could be fin rot, it's hard to say without a pic! The salt should help kill off the bacteria but I would try an antibacterial treatment like Melafix. That should shift it but there are other things available if that doesn't work. Make sure you increase aeration in the tank when you use the melafix and keep an eye on the water conditions. Do you know the ammonia and nitrIte readings? How big is the tank?
Ok will leave off with the salt!! I can't remember the exact ph reading ( took it couple of days ago) but it was within the normal range. Will the melafix be ok to use with just the normal filter or should I try to add extra oxygen another way?
Thanks for all the advice Eau. Fish is looking much happier ready. Fin looks healed (if a little bit bent out of shape!) and the red streaks less obvious. Will still get the melafix as a precaution though.
