In children, symptoms may depend on age: In infants younger than 1 month of age, symptoms may include having little or no energy (lethargy), feeding poorly, grunting, or having a fever. In children, symptoms of pneumonia are often the same as in adults. Your doctor will look for signs such as cough and a breathing rate over 60 breaths a minute.
Tap water should sit for at least an hour before adding any fish to the bowl. The water must be room temperature.
You also want to keep it on ice but not directly on ice. Meaning place some plastic wrap between the ice and the skin side of the fish. Usually three to five days. You can rinse the fish each day but there are some fish you don't want to do this to, like tuna, because you will wash away natural oils that help to keep it fresh.
