Red/pink mark on Banggai Cardinal

[design1stcode2n]

I have a cardinal that has been in QT for 2-3 weeks after TTM. It is eating and acting fine but there is a redish tinge as you can see in the photo and I wanted to get some opinions on what it may be.

Ammonia is 0, SG is 1.025, PH 8.0, temp is 77

Sorry for the quality i had to zoom in on my phone to get it.

Just realized I posted in the wrong forum perhaps, would a mod please move this to the fish disease forum if that is more appropriate.

how long has the blemish been there? Most of my fish's fin damage heals within a week or two. But if it's a skin infection it might be trickier.

I'm not sure I'd say a week. I guess I'll give it another week and scoop him up to get a better look. I was planning on dosing Prazi pro the last week or two of QT just as a precaution (not for this in particular).

That's a textbook case of fin rot. See here: http://www.chucksaddiction.com/disease.html

Further down under Fin Rot you can see a Banggai with a more advanced stage.

Thanks, I did a 40-50% water change last night and will pick up an anti-bacterial. Tested and I have a low amount of ammonia, going to cut back a bit on the feeding. I've been using Prime so its not toxic but still...

Also added a HOB filter and put the seeded media in there, perhaps it wasn't getting enough flow or the bioload was just too high.

I'm still detecting ammonia in small amounts. I'll just have to keep doing water changes until levels off. Started dosing Melafix last night.

Cardinal looks worse, I'm seeing more red on him, not sure what to do beyond what I'm already doing. I'm feeding once per day small amounts, water changes and dosing Melafix.

I took the cardinal out of the tank in the hopes of getting better pictures but they came out worse than taking pictures while he is in the tank. My phone shadowed it

The two clowns with him look perfectly fine and everyone is acting normally, eating and swimming.

After going trough my books I think it could also be a Vibrio infection.
You may need a stronger broadband antibiotic.

Bassleer recommends Chloramphenicol, Nifurpirinol, Sulfonamide, Kanamycin, Streptomycin or the like and states that combinations like Chloramphenicol and Nifurpirinol may be more effective than single antibiotics.

I have treated fish successfully with Septra before but used it as a in-tank treatment (if I remember right one 160/800 tablet on 50 liter) - in a hospital tank of course. Septra is a combination of Trimethoprin and Sulfamethoxazole.

Fish Sulfa Forte is Septra (Trimethoprin 160mg, Sulfamethoxazole 800mg)

Cipro would be another good candidate.

Fish Flox Forte is Ciprofloxacine in 500 mg tablets.

An update. Perhaps it was the lighting but I'm only seeing the small pink spot and it may have gotten smaller. Its hard to tell. After studying the Cardinal some more I don't think its Vibro.

I'm getting some algae in the QT so once the Melafix is finished I'll up the WC rate. It may just be do to water quality in a small tank. I don't think the biofilter was up to the task. No ammonia readings for the past couple of days so I have stopped dosing Prime.

If the clowns continue to look good I may move them to the display. They have been perfect from day one through TTM and 4 weeks of QT.

This will allow me to reduce the bioload and focus on the cardinal.

I'm not getting remotely the build up in the 29g that I am in the 10g QT so perhaps my CUC is working.
