A living world, beautifully contained.
Aquariums have always had a certain magic.
Light moving through water. Plants reaching toward the surface. The quiet rhythm of an underwater world unfolding just a few feet away.
The The OmniPaw™ AquaArc 3.5 brings that experience into a compact, beautifully curved 3.5-gallon aquarium designed for modern homes, desks and offices.
Ultra-clear GPPS walls create an uninterrupted view into the habitat, while integrated water circulation, oxygenation and multi-stage filtration work quietly behind the scenes.
Above it all, three lighting modes let you change the atmosphere with a touch.
Less visual clutter.
More of the world you actually came to see.
Clarity from every angle.
AquaArc replaces the boxy appearance of a conventional small aquarium with a smooth, curved profile designed to open up the view.
The 3 mm high-clarity GPPS construction gives the aquarium a clean, lightweight appearance while the rounded front creates a more seamless look across the aquatic display.
Fish.
Plants.
Stone.
Movement.
Nothing needs to compete with the tank itself.
Filtration built into the experience.
Beautiful water requires more than a beautiful container.
AquaArc integrates circulation, oxygenation and filtration into the aquarium system to continuously move water through its filtration pathway.
Fine filter material helps capture suspended debris, while activated carbon assists with common odors and discoloration.
The result is a cleaner, more refined system than a simple unfiltered bowl—with the essential filtration components already designed into the aquarium.
Three ways to see the same underwater world.
Lighting changes everything.
AquaArc features three selectable lighting modes, allowing you to shift the mood of the aquarium throughout the day.
Choose a brighter presentation when you want to appreciate the detail of the aquascape.
Move into cooler tones for a calmer evening look.
Or let color create a more expressive underwater display.
One aquarium.
Three completely different moods.
Grow above the water, too.
The integrated upper planting area creates another layer of possibility.
Compatible hydroponic plants can be positioned above the aquarium, allowing roots to interact with the aquatic environment while greenery rises above the waterline.
It turns AquaArc into more than a tank.
It becomes a compact living display—water below, greenery above.
Always choose plants that are safe and appropriate for your aquarium setup and livestock.
Designed around quieter everyday living.
An aquarium should add calm to a room.
Not mechanical distraction.
AquaArc uses an integrated low-noise circulation system designed to keep water moving while remaining suitable for everyday spaces such as:
Bedrooms
Home offices
Living rooms
Workspaces
Reception areas
and thoughtfully designed pet spaces.
The aquarium becomes part of the room rather than equipment sitting inside it.
Compact doesn't mean carefree.
AquaArc makes aquarium ownership more streamlined.
It does not make aquatic care disappear.
No aquarium is genuinely “self-cleaning.”
Healthy aquatic environments still require:
Proper cycling before livestock is introduced
Routine water testing
Species-appropriate water temperature
Regular partial water changes
Filter maintenance
Appropriate feeding
and stocking based on the needs of the animals being kept.
The integrated filtration system helps make routine maintenance easier.
It does not replace responsible husbandry.
3.5 gallons means thoughtful stocking matters.
AquaArc is a nano aquarium.
That makes it beautiful and space-conscious—but it also means livestock selection needs to be deliberate.
Different fish and aquatic species have dramatically different requirements for:
Water volume.
Swimming space.
Temperature.
Filtration.
Social grouping.
Salinity.
And mature tank conditions.
Do not choose livestock simply because an animal physically fits inside the aquarium.
Research the minimum long-term tank requirement for the exact species before adding it.
For species that require a larger aquarium, choose a larger habitat.
Freshwater or saltwater starts with the right setup.
The aquarium hardware can be incorporated into appropriately planned freshwater or nano marine setups.
But freshwater and saltwater aquariums are not interchangeable ecosystems.
Saltwater systems require additional attention to:
Salinity
Marine-compatible livestock
Water chemistry
Biological maturity
and appropriate equipment for the intended inhabitants.
AquaArc provides the canvas.
The ecosystem you create still needs to be built around the animals living inside it.
A cleaner approach to the starter aquarium.
No giant external filter hanging off the side.
No harsh rectangular profile.
No need to piece together every basic component before you can begin designing the aquascape.
Just a compact system where:
Filtration is integrated.
Water stays in motion.
Lighting is built in.
Planting becomes part of the design.
And the aquatic world remains the focus.
The OmniPaw™ AquaArc 3.5.
A little world. Beautifully alive.
