Something white on my corydora sterbai

Hi,

My corydora sterbai has something white on it for several mounts.
His grills are damaged too.

Others corydoras are fine...

Any ideas?

Thanks

What are your water parameters? Is the fish flashing at all?

He has this on the both side.

Any help is appreciated.

0 ammonia/nitrite.
Nitrates hard to read, from 20 to 40.

What do you mean by "Is the fish flashing at all?"? :icon_roll

flashing = rubbing on driftwood,decor, substrate

its possible since its on both sides, it could be he is getting scratched/rubbed when he goes into his hiding spot

20-40 nitrates is a tad high. I'd suggest you try to keep it just a bit lower.
Just because you haven't seen it, doesn't mean it isn't happening. I've learned this the hard way. Keep a close eye on where he hides... That might give you a clue. I don't think that's it, though, since the patches don't appear to be on the widest parts of his body.
Does he act differently than the other cories? Swim odd?
What do you mean when you say his gills are damaged?
What are his tankmates?

I try to keep it lower. Hard to say with API test kid. I ordered Nutrafin one for better results (I hope).

He act the same, but he's smaller than the others cory. Swim the same way too.

Tankmates:
Angelfish
Bolivian ram
Draft gourami
Draft Orange Cory
Heal. Raspboras
Platy

I attached the photos of damaged grills.

i don't know, but i have one with a similar looking thing. i have treated him with Furan-2 and hydroplex. neither of them have provided a cure, i'm not sure where to go from there. i had friend suggest using Praziquantel, which is pink, but i haven't been able to find it locally.

I have had a fair bit of luck with 10 minute dip with hydrogen peroxide 3% at 2ml per 5 gal.
Then place the fish back in the main tank and repeat in three day's if needed.
This seemed to work for me with a group of neon's that suddenly exhibited fungus though I cannot make any claim that it will help.I'ts just all I had on hand.

One of my sterbais has had a spot like that on his side for almost 2 years. Always eating, acting normal, never flashing.

Can it be some kind of infection due to barbell erosion?

did you lose any of those neons? so far everyone i've seen with this on the cories, they haven't lost the infected one.

Now I see some damaged fins...

I have a 2g hospital tank and Furan-2, T.C Tetracyclinem, General Cure and KanaPlex. Can I treat it with that? If yes - how?

Do I need the sand at the bottom of the tank or not?

I want to treat him with Furan-2 + KanaPlex.
T.C Tetracyclinem won't work with pH 8-8.2.

Thanks

I've had a cory who has had a small white spot on his nose for at least 6-8 months because i can't get him out of my 90G to treat him and he's fine. It's weird.

I have the same thing you have on my Sterbai Cory. It's on both of mines though. I had someone told me it's Dropsy and it's going to be fatal, said there is no cure. Soon it's going to die were the exact same words.

But it's been like this for a month and they're still swimming happily and eating as well.

I was given Pimafix and Melafix just earlier today but can't find my net to net out both cory and treat them. Not even sure if the Pima and Melafix will help at all.

They're still doing fine :)

I took a good look at that photo and I didn't see any grill damage that looked too severe, nothing that won't buff out with some mineral oils and a good shop rag anyways. :hihi:

Seriously though, I don't know what the issue is with the side of the cory, but from what I have read it might be a fungus. I have recently had some white bumps show up on a sterbai cory that is in my captivity. I'm not sure what it is, but it is on two out of three fish I bought several weeks ago. They never had barbells when I bought them and just started growing them in when this happened. I started dosing the tank with Melafix today and will see if that clears it up.

Here is what my fish looks like.

High nitrates may be part of the problem. Some microorganisms grow better when the nitrates are higher. I do not know if it is really the nitrates, or if the nitrates are simply and indication that something else is also too high.

Don't wait for the new test kit. I would be doing twice as many water changes, and make sure you are cleaning the debris from the tank each time, and keeping the filter clean.
