Actually I don't use any water conditioner since I have whole house filter system. It removes all the chlorine and metals and provides soft water with pH about 7.4-7.6. So in last 4-5 years I never had a problem with any of the ammonia nitrites or nitrates. I'm thinking may be they were not eating much for few days and the food was the factor in this case. I will try to vacuum the gravel and do 10-20% water change. will see...

So the nitrite spike is gone now?

Glad to hear he's healing.

Keep us posted.

yes, nitrite spike is almost gone.
Current readings:
nitrite - 0.25
PH - 6.8-7
nitrate - 10
Ammonia - 0

the black spots disappeared and they are swimming and eating like healthy fish. So, I think if I do 10-20% water change and test again in a couple days. After that I can put carbon part of the filter back.

Do you think he will grow the skin back or it will be a scar like this?

I'd probably do 25% on the water every couple days until the nitrites test reads 0 when done right before a scheduled water change.

I'm not sure if he'll completely heal back to look the same, but I think he will. It will just take time for that much regeneration. I'd add vita-chem and fish protector daily to speed that up as much as possible.
