Then why are you here? Seriously. One can technically keep an Oscar in a ten gallon tank. Itll die real quick but hey you proved all those suckers wrong anybody can be on you tube and ive met plenty of people that own fish stores that dont know their face from their elbow. But hey you do you, you sound bound and determined to get danios so good luckBigger is always more expensive and i dont trust you guys. I trust the professional that has a youtube channel and a fish store. Sorry but thats the truth.
