A long time ago I had a reef tank like in the late 80s and early 90s. Life changed had a family and work all toke over. Now I'm 76 and can't do a lot of activities like golf and climbing mountains. I still like to be active so I thought maybe a Reef tank would be of interest. I thinking the size of around 200 gallons. Since it takes a lot of work and dedication I would want to keep it going into a least my mid 80s. I know maintenance is a big deal to be successful. I'm curious what people in the know thinks about this for a old guy.
