well following the finger and playing with them isn't what I'm talking about. I'm talking about doing the changes yourself. A 10 gallon is HUGE, trsut me. I wasn't expectign it to take up half my desk. Plus 10 gallons of water per change is a lot. It's going to require multiple containers for me :/
Hence why if you're getting a 10 gallon, it might be easier for you to just put all the bettas in there to reduce the cleaning you have to do. Especially since cycled tanks, as Aokashi said, need to be cleaned 100% once a week, which is a LOT.
