Yes, from reading thousands of letters from readers about their fish, I am convinced that fish can live a lot longer than most people think - if only the fish parents can take better care of them - consistently throughout the life of the fish - clean water, everything else about the water correct - pH, temperature - correct plants and decorations and maintenance of these fixtures in the fish's environment - a healthy, appropriate diet - and believe it or not - emotional well-being. Pets - fish included- respond to attention, care, love, environmental factors, change, stress, tone of voice, facial expression - so many things - we could go on and on. Mainly, thoughtful and caring observation of them and attention to them and constantly arming yourself with knowledge on the subject of the type of fish you have - will go a long way toward the health and welfare and long life of your pet fish - as with everyone and everything else in your life. It is a joyful responsibility to be a fishy parent. Your fishy family member makes every day more delightful for you and your family. They just need care and consideration just like everyone else.
