Please help ID illness on Sterbai

Post by peddongom »

Hello,

I have been having a hard time figuring out what is wrong with two of my Sterbai corydoras. At first I thought that it was bacterial infection and it still could be.... but I’m not sure what kind. The have been covered with the white slime like patches for over a month and I have not been able to cure them. Sorry for the Algae on the glass.

Both Sterbai seem fine. They are active, they eat well and it does not seem to spread to fast on them. I have tried Paraguard with little effect. If anything it might have halted the spread but I can’t really say for sure if it has. I tried API General cure and E.M. Erythromycin, also with little or no effect. I am currently medicating the tank with ICH-X which was recommended to me because it can help with Chilodonella, if indeed it is Chilodonella. I have ruled out Columnaris which I have dealt with in the past.

They are in a 26gallon long tank with several other corydoras and a few Endlers. The tank is a bit crowded but that’s because it is only temporary until I move them into my 125gallon tank. All corydoras have been in the 26gallon long for almost 5 months. Water parameters check out fine since I do water changes twice a week. And every other day now for the past week since I'm dosing ICH-X.

Ammonia 0
Nitrites 0
Nitrates 0
Temp 75
PH 7.8
GH 4
KH 4

Substrate is ¾ Mr. Aqua soft soil and the right side is Flourite black sand.
Filtration is Eheim Ecco 2232 and spong filter.
Planted with Anubias, Java fern, Buce, Bolbitis
Smooth rocks and stones
Tank has been running for years (2008)
Food- live grindal and white worms. Omega one Algae wafers, Sera tabs, New Life Spectrum ect…

I use 50/50 tap/ RO water for water changes. Fish load is…

8 Sterbai
8 Arcuatus
1 Duplicareus
8 Venezuelanus
10 Similis
2 Emerald Green
12 Endler young as dithers

Strange thing is that bacterial infection and Chilodonella are very contagious. But no other fish seems to be infected. I’ve tried looking this up but the closest thing I could find that looks similar are these photos I found on Google.

I hope someone here could help me find out what is wrong.

Thanks in advance!

Reminds me of velvet.

When you are applying meds, are you remembering to remove the carbon from your aquarium filters?

Can you buy some ProForm C? It's sold for treating velvet and ich and similar ectoparasites in ponds, but you can use it in aquaria. I believe the dose is 1ml per 10 gal for 3 days.

Good luck, Eric

Thank you for the response Eric,

I don’t use carbon because of the plants in my tanks. I don’t think it is velvet either since the two Sterbai have had it for over a month and whatever it is have not spread to any other fish.

It looks bacterial. Send those photos to Seachem and see what they recommend. Let us know what they say.
