Just wondering, how many betta on average does you guys keep and how wonder do. U change water?
While waiting for the gurus to give better advice, my two cents thoughts.
Number of betta in a tank and how often to change water, I think both will depend on the size of the tank. I seen before videos of breeders breeding ALOT of betta all in a tank super squeeze. Some say its bad for the fishes, but some say its ok. You can see this video, the fishes seem fine.
So I believe if space is not an issue, the bigger the better. Afterall, they are fishes in the wild at first too.

Maybe u don't feed enough ??
This one I am still wondering too. Because online i read some say feeding for around 2mins, then say 5-6 pellets. But I feed both doesn't tally leh. Pellets can eat 1 piece each second, how to feed 5-6 pellets yet for 2mins...

I am mainly giving my betta flakes from the ocean brand. I notice some oil will start to spread the moment i drop the flake into the water, so what I do is hold the flake on a toothpick abt 1/2cm above the water, and the betta will jump up to catch from the toothpick. The flake size is about his eye, and I will feed abt 4pcs twice a day. Is that enough???
