It's the entire time the lights are on. It's just a 3-4 inch sarassa comet goldfish- one that had dropsy that I was able to save, that normally lives in a pond outside, so it's used to seeing movement from above. This was one of a pair that I posted a few days ago that I'd somehow unintentionally killed his partner while transferring him to the little indoor pond!
Once he was healed (this surviving one), I didn't want to throw him into the now icy water- I didn't think he would make it. So I set up a rubbermaid stock tank in the basement and decided to try overwintering my lilies at the same time.
All that work for a $5 goldfish, LOL. But when I first started to euthanize it because of the dropsy, I just couldn't bring myself to do it. And I used to be an animal control officer- you'd think I'd be used to it! I don't know why this little fish affected me this way! But I'm glad I tried to save him and I'm glad he made it (so far)!
