Hi friends, Which is better for a single male Betta, 1.5 gallons fishbowl or 5 gallons tank? I understand the 1.5 gallons fishbowl can have a weekly 100% water change, while a 5 gallons tank with filtration can have only a partial weekly water change. So, which is better for a Betta, complete water change or partial water change? Thanks & bye
