So I've had my betta fish that is a male. I got Mr. Cutie for my daughter for her 4th birthday March 7th 2018. I do not know how old he was when I got him though. He was purchased from Walmart. I guess for about the first year he was in a decent tank alone with a pump. He gets regular beta food from the store. I will be honest and say keeping a fish is never one of my strong suits and his tank has not been cleaned nearly enough. I think the last time it was cleaned was over a year ago. It isn't really that dirty in his tank honestly and that's without a pump too. I call him my little miracle fish because he's so easy to take care of. I've been debating cleaning his tank but honestly I am worried if I do at this point it will be bad for him. He seems adjusted to his living area and the water. I do keep it filled when the water gets low and he is still very active. I would guess he's around 2 years old from the time I bought him at least. So is he just a rare beta? Would you recommend changing anything?
