I've been looking at ecospheres, bottle biology projects and planted jars for years. I recently emptied a syrup bottle and thought about how cool it could look.
I cleaned it out really well and coaxed the labels off with nail polish remover, then cleaned it really well again.
I layered the bottom with a very thin layer of play sand from Lowe's, added decholorinated water straight from the tap, then took a small clipping of Hornwort from the
Guppy Tank and found a pond snail wandering around in one of the tanks. I then put the lid back on the bottle, closed the top and found a spot where it will get indirect sunlight.
The black spot on the side is Pete the Pond Snail
