Review on 🐠 Penn-Plax Air Action Aerating Ornament and Aquarium Decor with Air Bubbler Movement Enhancements by Amy Miller

This thing is cheap/thin but once I found out the bases were NOT suction cups and just covered them with aquarium gravel to make them heavier it worked great and looked pretty cool. Be careful when placing gravel under the base. If the "swing" gets gravel that rocks the skeleton back and forth, it won't move properly. You will also need a small valve in the air line to soften the bubbles or they will come out too quickly. It would be MUCH easier to install if they were on suction cups. Not bad for the money but don't expect anything special.
