Default Red streaks in fins

Hi i have an 180 litre tank which currently houses 2 fancies. One has red streaks appearing in his tail and 1 fin. Water quality is;

NH3 0
NO2 0
NO3 20
Ph 8.2

Temp 23 degrees

There has been no ammonia present in the tank as long as the fish has been in, he is not over fed (a few pellets morning and evening) i have tested the water about an hour after feeding to check for spikes and there is non. I have 2 filters set up so the water is very well filtered. What could be causing this and how can I deal with it?

It is either finrot or haemorrhagic septicaemia (blood poisoning). Either way you need a bactericide such as Myxazin, or salt at 10 level teaspoons/gallon (10g/litre) added gradually over two days.
But there has to be some kind of stress causing it, unless it's a new fish. Maybe your test kit/s are faulty (do you use strips or liquids?) or something airborne like air freshener etc? Do you use a dechlorinator for your water changes? How long have the fish been in the tank?

Thanks for the sugesstions on how to treat this. I am struggling to work out what is causing this. He is not a new addition to the tank although about 2 weeks ago a new fish was added but I had querentined the new fish for 3 weeks before adding to the main tank. Could it be the stress of having another fish to compete with even though the tank is big enough for the 2 of them? I use an API liquid test kit that is 2 months old at most and i always use a declorinator. Also there are no air freshners around.

Does the fish have opaque or white fins? I ask because I have a red fantail who has opaque/white fins and I can see some red veins in his tail. Are they veins or actual blood streaks? I was worried about the veins I could see in my fish's tail, but apparently this can be common in fish with opaque or white fins - it just means you can see them more obviously than in a black moor for example, who has dark fins.

If it's blood streak though there is a problem, but not sure what as your set-up seems fine.

My Red Cap Oranda has red veins in the tail fin, always has had them and has never been exposed to prolonged ammonia or nitrite. Try and get some photos and don't treat with anything at the moment

arent red vains in fins an indication of bacterial problems.?
i have expressed the benifits of adding a uv sterilize to the aquarium, for killing bacterial blooms etc.

All I know is that my fish had one red vein in the tail when I bought it a year ago and has had no health problems at all

i think the reason i worry is that he hasn't always had them an they do seem to fade then get brighter again so i don't think its just a vein. I have some melafix do you think this would help?
