Even Your Skeleton Works Overtime Down There
Your tank is quiet.
Fish drift by. Same rocks. Same plants.
Then you drop Finnegan in — and suddenly a tiny skeleton starts pushing a waterwheel, bubbles rising with every turn.
It never stops.
Your fish don't know what to make of him. Neither do your guests.

Hooks up to any standard aquarium air pump with the included tube connector. That's the whole setup.

Frequently asked questions
Does it need its own air pump, or does it come with one?
It comes with an air pump, so you have everything needed to set it up. Simply connect the included tubing and plug it in.
How strong does the air flow need to be for the wheel to spin?
A gentle, steady flow from a basic aquarium pump is enough. If the flow is too weak, the wheel slows down. Too strong, and bubbles rush past the paddles.
Is it safe for freshwater and saltwater tanks?
Yes, it works in both. The PLA material won't leach or rust, and there are no metal parts.
How big is it?
The base is about 4 inches wide and the whole piece stands roughly 4 inches tall. Good for tanks 5 gallons and up.
