The surface of your aquarium just got interesting.

Stillwater Tank Co. designs practical, playful aquarium accessories— floating docks, feeding and plant corrals, and custom pieces—then tests them in real tanks before they ever reach yours.

A planted freshwater aquarium with the Stillwater floating dock and boathouse concept at the surface

The Stillwater Dockwith Boathouse concept

48+hours float tested

A first look

Small details. Big living.

Coming soon

This is the collection taking shape at Stillwater Tank Co.—functional pieces for shrimp keepers, planted tanks and calmer aquarium setups. Each design moves from idea to print to real-tank testing before it is released.

The first collection

Lake-cabin charm. Aquarium logic.

We are starting with the overlooked space at the waterline: pieces that add function, enrichment and a little personality without turning your tank into a cluttered toy box.

Floating aquarium dock with a miniature boathouse

Float-tested prototype

01 — Foundation

The Stillwater Dock

A modular floating base that turns unused surface space into something useful—and gives future feeders, plant holders and larger accessories a stable place to live.

In refinement

02 — Statement piece

Boathouse Topper

Inspired by a lakeside bait shack and designed as one recognizable, brandable piece—without a pile of tiny loose accessories.

A rounded floating feeding and plant corral in a planted aquarium

Next in line

03 — Surface control

Feeding & Plant Corral

A rounded, stable surface corral that keeps food or floating plants where you want them, with easier handling and fewer tiny parts.

Made to solve a problem

04 — Your tank

Custom-Fit Pieces

Odd lid, awkward gap, breeder setup or one very specific tank problem? Custom sizing and functional one-off designs are part of where Stillwater is heading.

Print. Float. Watch. Refine.

A good idea still has to survive the tank.

One dock prototype stayed sealed and floating through a 48-hour tank test. The next round is focused on raising and levelling the waterline—not pretending version one was finished.

Build for the waterline

Buoyancy, balance and usable surface height matter more than how a model looks on a computer screen.

Test in real tank conditions

We watch for water intrusion, tilt, drift and how the piece behaves over days—not just the first five minutes.

Adjust the invisible details

Internal structure, weight distribution and connection points are refined until the finished piece sits the way it should.

Keep the final design honest

Finished products will list their material, intended use and care instructions. Prototype claims stay prototype claims.

“There has to be a better way” is basically our product-development department.

Why Stillwater exists

Built by staring at tanks a little too long.

Stillwater Tank Co. began with a floating dock idea and the kind of practical questions fishkeepers ask every day: Can it sit higher? Can it stay level? Can one useful piece replace five fiddly little ones?

The answer is a growing collection of small-batch aquarium pieces shaped by observation, problem-solving and repeated real-world testing. A little whimsical. Never careless.

Personality without visual clutter
Larger integrated pieces over tiny loose parts
Designs refined around an actual tank problem

Custom projects

Your weird tank problem is welcome here.

Not every aquarium is standard, and the useful ideas usually are not either. Custom project intake is planned alongside the first product release, with sizing and intended use reviewed before anything is made.

Coming with the shop opening

A straightforward request process for dimensions, photos, tank setup and the exact problem you want the piece to solve.

Good questions

Before these pieces enter your tank.

Can I order the products now?

The first collection is still in real-tank testing. Ordering will open after the final dimensions, materials, buoyancy and care instructions are locked in.

Will the dock actually float?

Yes—buoyancy is the starting requirement, not a bonus feature. Current prototypes have completed extended float tests; ongoing refinements are focused on how high and how level they sit.

What will the products be made from?

The exact print material and care details will be disclosed on each finished product. Stillwater will not label a prototype material as a final aquarium product before the complete design is settled.

Why avoid tiny decorative accessories?

Larger integrated modules are easier to handle, easier to find and better suited to homes where a small loose piece could become a choking hazard. The goal is charm without unnecessary little bits.

Will custom sizing be available?

That is the plan. Custom requests will need measurements, photos and a clear intended use so the design can be evaluated before printing.
