Cory With Sore Side

[Lynz781]

Noticed this red sore on my cory today. I was thinking it was an injury inflicted by my clown plec. The reason I think this is because I've seen him lunge at other fish when they get too close to his territory.

i had the exact same marking on my albino cory it dissapeared withing a few days.
i dont think its anything to worry about.

 

[Lynz781]

He's happy enough, no change in behaviour. Will just have to keep on top of the water changes. If you look closey at him, well I can, and I can see its quite a large area that looks "bruised" around the red area. It also looks as if the blood is under the scales. Hmmmmmmmmmmmmmm

Septicemia then, need a antibiotic fast, can you isolate the fish.
Antti internal bacteria med by interpet for the uk.

This info is taken off the board.
Septicemia: A fairly rare to common in all tropical and coldwater fish. It is caused by bad tank conditons and is very hard to cure if not impossible. Bacterial Hemorrhagic Septicemia can be diagnosed by red streaking of the fins and body and once this disease progresses, ulcerations and body sores start to appear. There is significant loss of appetite, lethargy, loss of motor functions in the later stages of the disease.

 

[Lynz781]

I could isolate him but I'm reluctant to do so. I have that treatment but I don't want to use it. I don't think I will ever treat the tank with meds again, ever since I nearly killed my fish with it. I think just keeping water fresh should help. Not too concerned just now, he's the only one that has it. Will keep an eye on him.

 

[WILDER]

He has blood poisoning and no way will water changes cure it, it can kill fast, plus he needs to be issolated, plus if he's issolated not putting the whole tank at risk, as if they peck on the dead body they will get it as well.

Not the writer of this information below.
Lesions, ulcers or sores on the body, reddening at the base of the fins and vent, loss of appetite and darkening of coloration are all symptoms of infection. Dissecting an affected fish often reveals an accumulation of fluid in the body cavity and haemorrhages among the internal organs. Ulcers may become secondarily infected with fungus. In very acute disease outbreaks, however, fish may die showing very few obvious external symptoms.
The bacteria responsible for this type of disease are often very common in the aquatic environment or as low-level 'latent' infections in otherwise healthy fish. However, outbreaks usually occur only in fish which are in poor condition for some reason, such as recent importation, rough handling or overcrowding. In a poorly maintained pond or aquarium, the disease can have devastating effects, as diseased fish released pathogenic bacteria into the water, which in turn infect other fish.

Hi Lynz781

I don't like the looks of that at all, and I think Wilder is probably right. It would be best if you isolated him and started a course of anti-bacterial medication.

I hope he recovers soon.

 

[Lynz781]

That side looks alot better today, less reddening. But I've noticed its starting on the other side. He flicks alot like he's itchy.
Side that looks better:

New red patch:

I would get treating him or you will lose him, sorry.

Wilder,

Is your diagnosis from experience that one of your fish has had this before?

I think you could be right or close with Septicaemia, however although there is red marks on the body there are none of the other symptoms yet like blood streaks on skin and fins, inflamed blood vessels, hemorrhaging around the eyes, sluggishness or loss of appetite.

Dermocystidium might be another option but thats quite uncommon apparantly??

Would leave it another day or two and see what develops, first sign of ulcer I would agree to isolate him.

Dave.

Bought 3 corys after my first batch, and they all died in few days, they have red sore marks on there bellies, ulcers and septicemia go hand in hand i'm afraid.

That link does not seem to state that ulcers are invariably a sign that septicaemia is present. It mentions septicaemia as a range of conditions that are LINKED with ulcers; doesn't mean any fish with ulcers has got the whole lot. It mentions parasitic flukes as another reason for ulcers. And it is about kois.

I do believe that Lynx's cory probably does have septicaemia, it looks like the illustration I've seen- and I'm treating my own cory on the assumption that its similar symptoms are septicaemia- but I do think it's important to read medical literature very carefully. Sorry, but I can't help remembering that the last fish you told me to euthanise is still in excellent health half a year later- however expert the diagnoser (and I know you are very experienced), diagnosis is always a tricky thing.

I think you are right in the present diagnosis, though- but not more because of your experience than because those links prove it. If I were Lynx I would definitely treat for bacterial infection.

 

[Lynz781]

Thanks everyone, but I've decided I'm not doing anything. Marks are gone and because of this, I decided I don't want to chuck treatment at the tank or him. Does septacaemia disappear like that? I don't know.

Burn from heater?

Maybe its embarrassed? )
