As you can see when you zoom in, most of the duckweed is white and dead.

I’ve been keeping fish and frog ponds for about fifteen years and I’ve never had such a wholesale dieback that even the duckweed carked it.

The feathery green plant seems okay so far. Fingers crossed that they make it. And, I hope that both the Azolla waterfern and the duckweed have left spores and seeds behind, that hopefully will sprout when we leave winter behind.

While you are zoomed in you may be able to spot the two remaing fish. Though they look like leprosy warmed up in the photo, in their analogue state they‘re stockier than they were, but at least still alive.

I moved their habitat back under the outdoor light, in the hope that that gives the plants enough light to survive until I get my grow lights. An added bonus is that I can sometimes see the fish flitting about from inside my living room.
