1/2-1 gallon of water depending on how many fry i get, for larger numbers. With water changes every few days. Otherwise i think the larger the better, but probably no more than a 10 gallon for 1 fish unless your dividing it. My male has a half filled 30 gallon tank to himself, he's a lucky fish, but it's a large tank for one fish.
currently i feed my bettas frozen bloodworms (conditioning them), also feed some live foods, mosquito larvae. I also feed pellets when I didn't breed them, though these ones went right into the conditioning phase.
I try to heat the room, otherwise the female at least is at room temperature, the male has a heater. i just contacted a person and i plan to get a couple small 1 gallon tanks with filters and heaters for the male and female after their spawn. they might even be spoiled and I'll try to split a 10 gallon tank for them if i can get a hold of one. Right now they don't have any filters, but i did add some air hose to the tank to keep it circulating, the female loves to play with the bubbles
, hopefully they will eventually turn into sponge filters when i get the supplies to DIY.
At the moment they get I'm going to say 75% water changes every 4-5 days. What i do is...Take my bettas out of the tanks, completely empty the females lg critter keeper(3/4-1g), and half of the half filled males tank(30g). Then i refill the males tank with a little more than i took out with fresh water and use the new water in the males tank to fill the females tank.
