Sick panda cory

[killrsheep]

Help me out please!

My Cory just developed some white fluff on top of his rear top fin and 2 mini holes on his tail

Water parameters seem fine
Nitrates 5 or less
Nitrites 0
amonia 0
Temp 27 Celsius
GH 70
Kh 100
Chlorine 0
Ph 7

I have Tetra lifeguard but I don't know if I can treat the whole tank or if I should isolate the guy
I also have some salt which is labeled for freshwater aquarium veterinarian use and a bottle of seachem stress guard
If I need anything else all I have is a nearby petco (Im.in México so think of an understocked petco) but I think they have antifungal and antiparasitic meds

[killrsheep]

Tankmates are 10 espei rasboras and another 3 pandas they all seem healthy but I've noticed the rasboras glass surfing and darting a lot since I introduced a new led light system 2 days ago (I just think it's stress)

By the white tuff, it sounds like a fungal infection. Fish can definitely be prone to any illness when they're stressed.
I wouldn't quarantine due to the fact that something like this is VERY contagious and hard to spot on fish with a lot of white, such as panda cories.
There's a medicine I got from Petco called API Fungus Cure. See if it's available to you.
As for the salt, I wouldn't recommend that. Cories don't particularly like it, which would cause more stress, and the benefit would be minimal in this case.

Ok, here is a better pic, I think it will be less compressed

So the holes may be from fungus too?

[DBradar3]

Are they holes or white dots?

[killrsheep]

Are nerite snails sensitive to those meds?

[DBradar3]

It may stain their shells a bit green, but other than that it shouldn't hurt anything other than humans if consumed.

[killrsheep]

It's a hole very Needle-puncture like hole

[DBradar3]

It's most likely the beginning of fin rot, which the fungus will also cause. The fin rot will usually start at the edges of the fins making them look more ragged, but it does create the holes sometimes too.

[killrsheep]

Ok, there seems to be azoo fungus treatment and Tetra fungus guard

[killrsheep]

And azoo anti fungus tabs

[DBradar3]

The guard is merely a preventative; it won't help your fish now.
I don't recognize the Azoo brand at all, but with those being your choices, at least the Azoo product is an actual treatment, and that's what you need.

[killrsheep]

Ok, thank you so much!

Should I remove purigen from my filter?

[DBradar3]

If your purigen is just bio filtration I would say no. You will have to remove any activated carbon however.

Fish illnesses are very finicky. I wish you and your little panda the best of luck!

[killrsheep]

Excellent, thank you so much, will update with results

Yes, Purigen is "chemical filtration" and absorbs impurities in the water much like activated carbon, except allegedly even more so. I would definitely remove the Purigen when using medication, as it will probably remove at least some of the meds from the water.

I'm not an expert on cories but I know that they can be sensitive to medications; Azoo doesn't seem to share the ingredients of their anti fungal tabs so I would err on the side of caution and use a half dose.

[DBradar3]

Thank you, UntimelyLord! I tried to look up Purigen, but didn't get much

[killrsheep]

Ok guys, here's the update


I hope resolution is OK, the fluff seems to be getting smaller and even though he is not swimming too much and his tail is a bit "contracted" his breathing seems normal, not to slow and not stress fast, so I think we are on the right track

[DBradar3]

That's great to hear! Continue to keep an eye on him and let us know when he's healthy again

[killrsheep]

He seems to be doing better


The treatment reads 3 days but I am going to carry on a second treatment with a 30% pwc per the bottle instructions, because he still has a bit of white on the right side, but he really gave me a tough time taking the picture he is an active fella
