I am never buying another betta online....this whole experience is too stressful.
Anyway, I got him around 11am yesterday and acclimated him over several hours before releasing him. His tank is 2.5 g, heated, used conditioner.
I keep the tank mostly covered with a towel to keep it dark.
Woke up this morning to find him partially out of the water because he wedged himself behind the heater. I moved the heater to the middle of the tank and he is now pale and just laying around, coming up to breathe.
What else can I do for him?
