Dear Ponomaru,
I looked at the pictures and watched the video.  The fish look thin and the slim coat has discolored which could be because of either a water quality problem of just because the fishes immune system is weak.
I’m not sure what the problem is, so I’ll give you a couple suggestions and ask a bunch of questions.

1)   I saw what looks like a metal screen on the wood structure.  If it is metal then that could be your problem because Corydoras are very sensitive to heavy metal poisoning, so even the smallest amount of rust can make the fish sick and kill them.  If it is metal (even stainless steel) take it out of the tank and do a major water change.
2)   Occasionally, fish get worms in the digestive track which can make the fish stop eating or just be thin.  Are these new fish…or have you had them for a while??  You could consider using a De-wormer if the fish are new.   Or if they are wild caught fish.
3)  What kind of filter are you using??  What is in it??  Does it have any metal exposed to the water?
As a first step take the sick fish out of the tank and put them in a quick (5 minute) potassium permanganate dip and then put them into a new clean hospital tank with low TDS water.  You could even add a couple almond leaves.

You have a really nice looking tank but you may want to add more live plants to control water quality and keep the fish unstressed.

I hope that helps.

Best Regards,

Bob

1. it's made from grade 304 stainless steel kub
2. I think they maybe WC kub  n032
3. External Filter kub and use ceramic ring biological filter media


Thanks a lot for your suggestions kub khun Bob  [on_045]

เอ๋ ผมพึ่งรู้นะว่าเค้าแพ้โลหะด้วย

งี้ติดชิลเลอร์ได้มั้ยครับ เหมือนว่ามันก็ใช้แทงค์พักโลหะทำให้น้ำเย็น?

คุณบ๊อบนี่มีความรู้อะไรใหม่ๆตลอด  [เจ๋ง]

Thanks for the info.
1)   I’d start with taking the sick fish out and using the potassium permanganate dip.  Then put them in a new tank and see how they do for maybe a week.
2)   Take out the stainless steel screen in the main tank.
3)   Do a 60% water change in the main tank.  Wait a few days and do another smaller water change.  Even better….if you have aged water do a complete cleaning and water change.
4)   Add more live plants.  Anubius would look nice in the tank.
The ceramic rings shouldn’t be a problem but check that the external filter doesn’t have any metal parts in contact with the water.

Chillers shouldn’t be a problem if the contact area with the water is made of titanium.

Hope that helps.

โอ้ ได้ความรู้ๆ ของแมนเมดทั้งหลาย ไม่ใช่ของที่ปลาต้องการ!!

Attn: ponomaru,
Sorry the fish didn’t survive, but you may want to make the changes to the tank design anyway to help the remaining ones.  Do a couple water changes with good quality water and they will all be happier for it.

25- 27 C  is a good average temperature range to have for most Corydoras.
