After the great goldfish disaster of 2015, we decided to scale back our ambitions and only try to keep a half dozen goldfish alive. That has seemed like a much better plan; instead of mass die-offs, we've had about one die per month, so we're down to four. But they seem happy enough. It's hard to get a picture of four goldfish swimming in a giant black tank in a basement. This is the best I could get:
So just imagine these guys. Times two. But much happier with their lives because they've got 150 gallons of water to hang out in.
Next step: edible fish!
