This is something I’ve thought about a lot since my wife passed away in February . Any of us can go at any time for any reason . I run almost every day and “ think “ I’m healthy but cancer or anything could be lurking undetected . I’m as weak as a cat in my arms . I can’t do even one push-up without tremendous effort and doing my water changes now I use a smaller bucket and make more trips . I’m going to try to keep up with the hobby for as long as I can but the day I can’t keep up may come upon me as a complete surprise . Now about the fish . What happens to them ? My best friend had a fishroom crammed with dozens and dozens of killifish aquariums and containers , all full , when he died eight years ago at age 62 . I don’t know what his wife did with them and don’t want to know but I think it’s a safe bet that , unbeknownst to us , when our time comes , our fish might just get unceremoniously flushed down the toilet . Bearing that thought in mind I plan to slowly scale back but still keep one small easily managed aquarium for my personal satisfaction .
