ok, i had 2 male bettas , each in a 1 gal bowl, well i was at wal-mart today , looking at all the bowls and tanks they had, there was lots of shapes and sizes for bettas. down to a 1 quart bowl, then i seen this "betta bow-front double tank kit has a divider in it, , well i got it , as it would fit nice on my desk, but i bet it dont hold a 1/2 gal of water, maybe it do. but no more. i have never seen a betta flare, so i thought it would be cool. it do have a thing to slide into the divider so that the 2 cant see each other. one flares up nice, the other just hangs around.
so is this ok for the fish to be in such a small tank? and if so, how often should i change the water? the gal bowls i changed every 3 days.
any input is welcome
