I need Help sick fish

[Hellothere12]

Hello I have a quick question and I come to r2r BC one everyone here is amazing much better ppl here on r2r then other forum sites! I would like your feed back on my sick koi, yes my freshwater koi! I been in the hobby for quite sometime now and I just got into keeping koi! the fish I got off ebay came in looking amazing but he seems to have a red bloody pelvic fin I cannot heal! Hes in a QT and has been since I got him. He is eating 3 times a day and I have been doing water changes every day unless theirs medication in there, I have used Prazi pro like I do on all my fish then after that treatment I added salt to his water waited a week (didnt help) still adding salt after water changes and now its been one week of using Kanaplex! but that dam pelvic fin looks red and bloody!!!! My next move is Melafix! Im most worried bc im thinking its hemorrhagic septicemia (Kanaplex says it treats it ?!?) but then again i read stuff online saying there is no treatment for hemorrhagic septicemia Im puzzled anyone has any thoughts and thanks for putting up with my Freshwater fish question! The 150g SW tank is still up and running btw lol

This is common in koi and goldfish when they have a reaction to poor water but mainly notates a combination of fungus and bacteria. While Kanaplex can work in saltwater with fungus, its treats differently in FW due to water density. I dont know if it is still used but there was a term for this called red pest infection.
Best treatment would be maracyn 2 along with melafix
If you are treating large water volume, you can use tetra medifin which is what I used on my koi and shibunkins

"Hemorrhagic" means "causes profuse bleeding" (often via tissue destruction), and "septicemia" refers to a serious full-body blood infection. I'm not familiar with the disease, but I can guess from the name that it is not a disease which causes fish to have a red fin, and nothing else, for multiple weeks. More like the sort of thing that fish die within hours or days of showing symptoms of.

Have you checked your water parameters?

You can (and generally should) do water changes while medication is in the tank by dosing the meds into the new water before adding it.

I had a pond for 14 years- this is not hemorrhaging but infection. Every once in a while my koi got this especially with changes in seasons and used something called tetra mediFin which has similar ingredients to what I recommended

Right, that's what I meant. OP said they were concerned about hemorrhagic septicemia, so I was saying that I don't think a disease called "severe blood infection that makes things bleed profusely" looks like a red fin and nothing else for several weeks.
