The biggest frustration for a fishkeeper is when a fish suddenly gets sick or dies.
Among fish hobbyists, the death of a fish which one has cared for every single day is a very sad event. In most cases, fish death is inevitable. Of course a fish is a living thing and its life will end. I have always told other hobbyists that fish death is part of the hobby. I always joked that if you don’t want to experience the sadness of fish death, keep a pet rock and it shall be with you forever. To some extent however, fish death may be averted if you are quick in analyzing the situation, and fast in making a decision and taking the right action. Thinking on your feet may save your fish from death.
