Sick Betta

[Romasia1]

My betta had flaky scales and all its fins were torn. Can you tell me the reason? Thank you very much.

Can you post a photo and/or video of the fish?

Any information you can give will help -
What size tank?
How long had the tank been set up?
What are the ammonia, nitrite, nitrate and pH readings?
How often and how large were the water changes?

How long have you had the fish for?
