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.
One Of Our Most Reordered Tank Ornaments This Year

✓ No batteries, no cords, no worry
Hooks up to any standard aquarium air pump with the included tube connector. That's the whole setup.

Made from fish-safe PLA with no metal parts and no dyes leaching into the water. Rinse it, drop it in, done.

The weighted rocky base holds firm on gravel or sand. No floating, no tipping, no chasing it around the tank.

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.

Does the denim paneling feel stiff to wear?
No. The panels are placed at the neckline, lapels and sleeves to hold structure, not across the body. The parts that touch you most are soft ribbed knit.
Can I wear this as my actual jacket in fall?
Yes, in mild to cool weather. It's a substantial knit layer, so think crisp fall days over a tank or tee rather than deep winter.
Will the knit stretch out at the elbows and hem?
The ribbed construction is built to spring back, and the denim panels take the stress at the sleeves and edges. Hang it rather than folding it to help it keep its shape.
Does it close in the front?
It's designed as an open-front layer. That's what lets the denim lapels frame the outfit underneath.
