Hi! My four year old wants his first pet and we have agreed to get him a Betta. We had a lot tanking experience- mostly saltwater- in the past but it has been a long time! When we moved we kept our 55 gallon freshwater tank due to minimal maintenance. That tank is.... gosh... 8 or so years old. I can't even remember. Needless to say- it's been a LONG time since I had to cycle a freshwater tank... I don't recall what we did as it was our first tank- I think we might have killed a couple fish in the process back then. Anyhow---- taking my son to pick out a tank/decor etc today. We will probably get a 3 gallon set up. What is the quickest way to make it acceptable for a Betta to move in?. I've never fishless cycled a tank before and I'm reading that can take up to 2 weeks. I don't want to wait that long ( I know, I Know) I would love live plants but um... plants aren't really my thing as far as not killing and I don't want to worry about purchasing a light appropriate for them. I want to do this as cost effectively as possible. I could move water from our existing tank? (if so-it's past it's time for a water change--- better to move water after change?) I could just let the tank run a couple of days to make sure everything is working well, buy new betta this weekend and make sure to do frequent mini water changes for the first while? Thank you!
