You could also make a floating plant island by filling a couple of milk crates up with empty water-tight bottles, zip-tying them together and turning them upside down. Then put couple of shallow pots and maybe a couple of rocks on top and voila! instant island!We will see how things go in the Spring. I wonder if the lilies will end up dying, since the leaves never get a chance to grow? I've been thinking about a little floating island, to provide some shelter in the absence of lily leaves. I have these cool plastic geometric floating grid things. I think Yshahar mentioned them at one point. You can connect as many as you need to get the desired size and approximate shape. I think I might put together 6 or 7, then try covering with some underlayment fabric. It should stay wet, since it will be lying right on the surface of the water. I thought maybe I could pat some moss down on the fabric. If it works, it could be kind of cool. Floating shade and shelter that might look like an island or a rock. We will see. It really isn't necessary, since the fish have two big caves to hide in. But they might like it.
I have those little plastic grid things, but haven't tried them out yet. They're meant to float just below the water surface, so as to be almost invisible, but I read where a reviewer on Amazon but a layer of bubble wrap underneath them so they would float better.
