Very sad to see that my cory is dying almost everyday.Search alot of website about this disease in cories but can't get any good information.
Really appreciate if can help.
Thanks a million inadvance.
Really heart break to see my cories leaving mi.

Hi!

Please give us more information regarding the tank size and number and name of the habitants!
What are the water parameters?
PH/KH/GH/ nitrites and nitrates, T°?
How much and how often do you do water change?
Cheers
Yann

Hi Yann, sorry for my late reply.
Everythings are fine now as i try to change my water everyday at about 40%.
There's still dying rate but it stop after a week as i change my water everyday till the 5ft day.
My cories are staying in a 3ft(lenght) x 1.5ft(width) x 1.5ft(height).
PH 7.5
KH 1.5
Temperature 26.7degree celcius
Presently i'm changing my water every week at 20%.
Question:
If the disease strike again, what should i do??
Recently just add in 100gram of coral chips, will it do any harm??
Now i left only
4 albino cories
5 similies
4 panda
2 milini
4 sterbai
2 paleatus
2 high fin albino cories
6 pygmaeus
1 agazissi
Decided to introduce concolor and goldline. What you think??
Thanks amillion for your help.

Hi!

I think your tank is already pretty crowded in the bottom...
A new tank t house soemof your population should be a good idea...
In cas of a new outbreak of the disease, you shall use the medication to cure the hole in the head disease. I don't know what it is mad of so be careful it is not harmfull to scaless fish. In that case case you might want to use less of the recommended dose...

Don't know exactly what that is, but sounds like something that adds alkalinity, making the water harder. Your pH is allready in the high end, so i would not mix corals and cories.

Also, i find the idea of adding more fish to be a bad one. 30 cories on 9 species must be enough bottomdwellers. Do you have other fish than the mentioned in the tank?

Glad you got rid of the disease! - So terrible to see fish suffering
