I can't find my thread :c.
But anyway he is in quarantine now the water tested out 100% safe. The issue was overdose of chemicals and stress.
We're using bettafix to help him out. And I was highly advised to get gravel so I'll be getting gravel on friday.
I also got an aquarium vac and when vaccuuming the debris most of the water was taken too so I did an unintentional water change but maybe it's for the best anyway.
Dahvie is in a betta cup right now and floating in the tank to keep the temperature right. I have the cup tied up so it won't sink.
He is already looking better but I'm still going to do as instructed and keep him quarantined for 7-10 days.
