Betta not eating for 3 consecutive days, what steps should be taken in order?
I just set up a 20L tank, my Betta hasn't eaten for 3 days. Please provide a quick check procedure to handle it correctly.

Summary20L tank, temperature fluctuates 25-27°C, pH around 7.2.
I changed 20% of the water yesterday but the fish still refuse to eat.
Brothers, give me the priority check order:
1) Temperature and pH
2) NH3/NH4, NO2
3) Is isolation and increased aeration needed?
