What is wrong with my goldfish? Please help. They both have lines of small white dots on their sides. But one of them also has a red spot and red in his tail . What is wrong and what should I do? They also seem very un-energetic and don't move as much as they used to.
What size tank do you have them in? Is it filtered? Do you know what type of goldfish they are?
Do you know your water parameters for ammonia, nitrite and nitrate? If you can answer these questions we will be better able to help you.
