These round moss ledges are 2" in diameter, and are printed on aquarium safe PLA filament.
Moss ledges are a great way to propagate your moss, while adding surface area to your aquarium. Just trim up your moss, and tie it to the ledge...it's that easy!! The quality of these ledges are 2nd to none, and are strong and clean looking. We even tested suction cups, so that we could provide the best suction for the ledges as possible (I hated having crappy suction cups that would let go and let my moss drop down to the substrate). These ledges will not turn, fall, droop, or break while tying (something I was having issues with buying from other vendors).
Plant Ledges with moss growing are also a great way to feed your shrimp, if your snails like to take over when you feed on the ground. I noticed with my snails, they don't climb the walls to get to the food if you feed on a moss ledge, so the shrimp have full reign of the food.
