Pond in a Jar – Update 3

Almost three months since the original collection, and it’s still thriving! OK, I’m down to just one beetle (that I can see), But there are still plenty of snails of various sizes, and that little sprouting plant has taken over. It’s over six inches tall, and has several side roots and offshoots. I really have to wonder where all the nutrients are coming from. The other plants don’t seem to be growing or dying off, and there’s no sign of any change in the soil level. And I’m keeping it sealed – it’s been a couple of weeks since I last popped the top. The water still has a greenish cast. I wonder if that’s algae floating or sticking to the glass. I don’t intend to shake things up to find out.

I wonder if it will make it through the winter – the heat in the room gets really weird; I sometimes have to open the window to keep from baking.

I tweaked the image a bit to better show details.
