So I finally decided upon a betta fish,and went shopping for supplies today. I got a tank, some silk plants and gravel for the bottom, heater filter, food, etc. But, on impulse, I spent 9.99$ on moss balls… ha. Anyways the water testing kit and water conditioner won’t be here for several days, so the marmios are living in their little cup still. Anything I should do for them?? Water changes?
