Also going back to a previous thing with one of my tanks. In the window tank, some of its plants haven't been doing so well. I reverted to the old backdrop I'd originally used. It was just a piece of cardboard with dark cloth draped over, that sat behind the tank and usually tipped so the top part leaned away from the tank onto the window pane. That let more light in from above. I think the plants have been missing that extra amount of light- so I took off the black plastic that was currently taped across the back of the tank tank wall, and returned to using the tipped cardboard. This means there's a now strip of light across the top:
With the late-season heat this week I've been finding more caterpillars in the garden, and a few more mosquito wigglers. Yesterday I gave Perry at caterpillar that I thought might be just a bit too big for him to handle. He bit at it repeatedly, with that little excited waggle of his tail. Finally got it down. He likes fighting for his food! He's doing loops across the tank when I approach again.
