    I wasn't talking about O2 depletion though, I was just talking about CO2 poisoning. It's definitely possible to have too little O2 in your tank and suffocate your fish, but getting too much CO2 in the water is quite hard. And while a betta won't die from O2 depletion because they can breathe from the air, they can be poisoned with too much CO2.
    But yes, adequate flow in a tank is definitely a necessity.
