Thank you!
I'm so happy the tank turned out as it did--I was on a budget (who knew a free rescue fish would have such a price tag????).
The blue bowl is high-fired ceramic that I made in a class. I thought I'd start my first plants in it, in sterilized soil covered with rocks, but they don't seem any happier than the ones I just plunked in the substrate.
The little pumpkins are glass, given to me on Halloween. I hope they are non-reactive. If I find out where they came from, I'll post it here.
