Hi ,
Had trouble with our fish and 7 of them died in the past month . Anyway the last remaining goldfish has had a black spot on it & today he has several all of a sudden . The water is fine . What do I need to do ? Thank you. George

What size is your tank, what are the water test readings (Ammonia, Nitrites, Nitrates). The best thing to do when a problem arises in a tank is to do water changes or multiple water changes. Goldfish are heavy waste producers.

You have forced you fish to breed by temperature changes but there is no male.

How do you know that when he didn't mention any temperature change?
