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 feed only the amount of food your fish can eat in about five minutes. You do not have to track it to the second, but any food uneaten in about five minutes will probably just rot in the tank, so siphon or net out the excess after five minutes, and learn just how big a pinch is right over time.
