Both tanks are the same really. 10g reasonably planted, weekly water changes, water temp 26 (although they usually sit around 24), add stress coat and stress zyme at water changes, Henry has three emerald green corys, Aqua one betta pellets and bloodworms, had them about a week, no signs of ilness. Hope that helps :)
