thank you phillydog1958 for ur fast reply
i change about 10% of water every 2 or 3 days with old water
and i have lot of drift wood in the tank
i didn't see any fish come near to it really but when it goes dark at the night i hear a lot of booch and taak and boom in the tank

If your not noticing any aggression it is possible it hurt itself on the driftwood (looks like it's missing scales aswell) as the tank is not very big. Clean water and it will heal fast.

aidenb thank you for advice i'll do my best with water and i'll plan for bigger tank soon

You may wanna remove some driftwood, with aro's you want an open tank so they do hit anything if they get spooked.

well..... if that aro is in the 66 gallon tank you are listing . that's the first problem.

It doesnt look like fin rot. Looks like somethings biting at his fins. Could be one of the 3 bichirs you have. Or the upside-down catfish.

and how to cure it ???

if its the other fish. only thing you can do is remove the other fish or remove him.
I suggest buying another tank.. Much larger tank.
