Reddening/blood To Base Of Anal Fin

[KingKenny]

I'm currently in the middle of treating my fish for whitespot after my wild caught Pseudotropheus Acei or Synodontis Petricola bought it into the tank with them.

I've been treating with Protozin and have started my second round of treatment.

I got back today and noticed that one of my acei has very noticable reddening/blood spots where its anal fin meets it's body. There is absolutely no damage to the fin itself, just this area of reddening/blood spots where the body meets the fin, along the entire length of the fin.

Water quality is spot on. Ammonia 0, Nitrire 0, Nitrate 15. It's hard to decribe the actual reddening, but it does appear to be blood.

Would this be finrot? I can't understand why if so as the water conditions are good and it's only at the fin base.

What's the best course of treatment considering I am already using Protozin. Can I still use Melafix?

I haven't been able to get a picture but the reddening is very much like my crudely edited Microsoft Paint picture below. There are clear larger blood sports reasonably evenly space apart with smaller areas of reddening between.

It's septicemia and hard to cure once it has progressed, and the meds on our market are not always strong enough.

Red spots on skin can be caused by:
Regarding the small red dot, small pinprick like haemorrhages (called petechiae) can be due to a local lesion, a generalised septicaemia or toxaemia caused by acute viral and bacterial infections


Anti internal bacteria med by interpet treat septicemia, but to be honest it's not a strong med.

How sure are you about that? The spots appear to be where the 'ribs' of the fins meet the base.

If theyare blood spots the fish is ill, i doubt red blood spots are it colouring, its septciemia blood posioning.
