I currently have a 10 gallon tank setup that's doing great and am getting ready to add a betta. I have an Aqueon 1 gallon Mini Bow I'm planning on quarantining him in before I add him to the 10, which houses cories. I was wondering which is more important, having the filter in the tank or giving him more room to swim around. The tank will have gravel and some anacharis (from my 10) for decor in it. Also, how long would you all recommend quarantining him before moving him to the 10 gallon?
