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.
How long do you let the water sit before you put the fish in the tank? Before you buy a fish you need to cycle the tank, meaning you need to put the water in, turn on a filter that is big enough for your tank, and adding water-safe (a dechlorinatâ¦or) to the tank and letting it run for 24 hours.
