Corydoras Panda need HELP

[thief4eg]

Young fish (1.5cm). A week after the purchase, the abdomen and eyes increased. They were treated with hydrops(Bactoforte S), a week later, strange substances appeared on the side of the fish.
The fish eats well, swims, does not hide!

Help identify the disease.

What is it fed?

What is it fed?

Small bloodworm(frozen packaging) + Tetra Wafer Mix

Looks suspiciously like lymphocystitis...but as with everything I stand to be corrected (and probably will be corrected)

...Or is this an illustration of those 'fatty lumps' cories get, when fed too much protein-rich foods?

That's what I thought Bruce but the food given isn't causing such I'd say.

The bulging eyes means a pressure build up of some sort inside the body . But what is causing it puzzles me in this case.

I can't help but get distracted by that substrate, which is wholly inappropriate and will accumulate all manner of decaying matter.
That said, whilst we know what is being fed, we don't yet know how much, @thief4eg .

The aquarium is young, 2 months old ... The disease is caused by nitrites (0.4mg at that moment) I think so.
Now all water parameters are ideal (ammonia and nitrite is 0%)
I thought the scales had detached, the fish will grow up and there will be new scales, but today it does not look like scales!

There is a contradiction here.
Are you saying that your nitrites were high when the symptoms appeared?

Excess ammonia, nitrite and even nitrates can cause an excess of mucous secretions, while the fish tries to protect itself against the toxic and burning water.

Just to eliminate the fatty deposit theory, could you please clarify your feeding?

There is a contradiction here.

The problem started 2.5 weeks ago ... When the fish got sick, there were nitrites in the water.
For a week, the water parameters are good: nitrite / ammonia = 0, nitrates = 4, phosphates = 0.25

Just to eliminate the fatty deposit theory, could you please clarify your feeding?

When I don't have time I feed Tetra (half green and half orange) for 5 Corydoras and 1 Ancistrus.
At other times I defrost bloodworms, also once a day.

True but it is not the quantity but the quality causing such issues.

Understood.
What about pH and water hardness?

What about pH and water hardness?

Water osmosis, change once a week 25%
Gh=7-8
Kh=4
PH=7-7.2

 

[thief4eg]

I think the disease is caused by stress and nitrites. Immunity has missed what's in the body, but what IT IS .... And can it be cured. The fish lives in a common aquarium, all fish look healthy!

 

[Bruce Leyland-Jones]

So I think we might have 4 options;

• A nasty case of lymphocystitis virus.
• Fatty lumps from a less-than-perfect diet.
• Excess mucous, from something in the water irritating the fish.
• Cancerous tumours.

NOTE that symptoms do not have to indicate a disease, merely a reaction to something that is not a pathogen.

If bacteria/fungus was involved and/or the immune system of the fish had been compromised, then aquarium salt would assist.
A dose of 1 tablespoon per 5 Imperial Gallon would be a suggested dosage, to begin with. Normally, a therapeutic dose would be 1tbsp per 3 Imp.Gal., but care has to be taken with some Corys.

IF it's the virus or any other pathogen, then your other fish, whilst looking healthy at the moment, will likely have it.
Aquarium salt is a lot safer than adding medications, without knowing exactly what it is we're adding medications for.
