I’ve had goldfish for years, and honestly, they can be super quirky! Chasing around is pretty normal for them, especially if they’re feeling territorial or just hyped up during feeding time. As long as no fins are torn or anyone’s hiding all the time, it’s usually fine. Cloudy water happens to me too if I overfeed or slack on water changes—it’s just part of having goldfish since they’re so messy. I’d say keep an eye on how much food is left floating around and maybe try the probiotic food to see if it helps. A decent filter and regular water changes are what keep mine happy and healthy.
