Help With My Puffer

[tommyg123]

Hello

I've had a figure of 8 puffer fish for a good year now and hes been fine up until now, the last 2 days he has just been staying at the bottom of the tank and barely moving around and hardly eating anything...

I've done water changes/tested the water and everything is as it should be.

does anyone know what i can do?

Are these in brackish water?

What other water parameters?
