I tried tying some of my middling Java moss to the branches. It looks nice, if a bit yellow, I'm not sure it will last. Not a big deal if it doesn't, just practice. It was fun!
I also found what looked like a baby pond snail crawling around on my glass. I removed it, but now am left wondering if there's more hiding about. I certainly hope not.
Luckily, the package I ordered showed up today, so I added a "biologically active" filter sponge that claims to speed up or eliminate the need for cycling. Seems a bit too good to be true but hopefully it shaves some time off!
