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.
The whiter the fish and the less oily it is, the longer it keeps as a rule. Mackeral and bluefish are hard to keep for very long, Cod, snapper and fresh water fish like catfish, walleye etc keep a long time on ice(7-9 days). Ice is the key. Put the fish in a bowl and set a waterproof bag of ice on it.
