Hi! I'm new to this site and I've tried to hunt around for an answer to this question before posting, so I'm sorry if this is has already been asked.
I recently bought two new betta males for my two 1 gallon tanks. I know most people recommend at least two gallons, however, I am dilligent about water changes and always look for a healthy but smaller fish. I was wondering though if anyone had a recommendation for a small filtration system. I still plan to change the water when I should but I love my little guys and was just thinking that a filter wouldn't be a bad idea.
I have had bettas in these tanks before and they thrived with very little care other than feeding and water changes (one lived for 1 year and the other lived for almost two). I am currently trying to expand my knowledge of bettas so I can provide them with the best care possible.
Thank you to anyone who has time to help me!
