Age is not the issue. The issue is owning a monster fish and being responsible for it. I started with Betta's as a kid. I had guppies, swordtails, but they lived in a 25 or 50 gallon. Now I have my 3 ID's My avitar picture is an old shot, he is 8" bigger and has a 24" ID with him. It is being aware of the resposibility of your species. Life span is never talked about and should be. After 18 years, I have no idea how long my ID's will live, but they are mine for life. I am just disappointed in people who don't think ahead of the issues they will face, owning any kind of monster fish. It breaks my heart to say no to my LFS when they ask me to take home a big fish that someone finally realized was beyond their limits. Hopeully more people will read this thread and realize what I am trying to say. Im not trying to discourage people, or offend. It is just the opinion of a dedicated monster fish keeper, trying to improve the lives of other monster fish, and the people who may own one.
