These moss squares are 3d printed by us. For attaching plants such as mosses so the plant doesn't end up floating throughout the aquarium. These do not have the ability to be attached to a suction cup. We have been using our 3d printed moss squares for years with no issue. They are fish, shrimp and snail safe.
