Pawfly Hanging Aquarium Plant Holders

Pothos, peace lilies, bamboo or anubias can grow with roots in the tank water and leaves above it in these Pawfly planter cups. Each cup is 3.1 by 2.1 by 5 inches, made of polypropylene, with slits and holes in the bottom so water moves around the roots. The set holds 4 cups, each with 2 detachable hooks.

Slide the hooks into the top slot and hang the cup on the glass. They fit rimless tanks with edges up to 0.39 inches thick, so a framed tank with a plastic rim is not covered. Add pebbles or gravel to steady young roots. Inside the cup, the roots sit out of reach of fish that nibble them.
