Friend’s sick betta

[Periwinkle19]

My friend has two betta fish. One of them died today. We can’t figure out what’s going on so I seek help here.

The symptoms are:
-not eating (it’s been a week now)
-swim bladder
-stays at the bottom of the tank and only goes up for air

My friend has tried everything, epsom salt baths, treated for parasites, betta fix, almond leaves, and even upgraded to frozen food. A concern she has is the hard water in the tanks. She’s currently attempting to fix it and she tested the pH level. The result was normal. If anyone has an idea, we’ll be grateful.

Could you please answer the following questions?

1. What are the parameters of the tank? (pH, nitrate, nitrite, ammonia, etc...)
2. What size is the tank?
3. Has the tank been cycled?
4. How long has the tank been established?
5. Did you do a water change?

Thanks!

Can you post a clear picture of the fish and a short 20 second video of it swimming or trying to swim?

Try doing a 75% water change and gravel clean the substrate each day for a week. Make sure any new water is free of chlorine/ chloramine before it is added to the tank.
