The Fluval Siena 332L Aquarium is a premium complete aquarium system combining generous dimensions, powerful filtration and sophisticated app-controlled lighting with contemporary furniture styling.
At 110cm wide and 55cm front-to-back, the Siena 332 offers excellent swimming and aquascaping space without requiring the 120cm footprint commonly associated with larger aquariums. Its matching furniture cabinet conceals the filtration and pipework, while Fluval’s Easy-Connect system allows the aquarium to sit neatly against a wall.
Complete with a Fluval 07 Series external filter, M Series heater and two Plant 4.0 LED lights, the Siena 332 provides an impressive foundation for a substantial tropical or planted freshwater aquarium.
Fluval Siena 332L Aquarium with Easy-Connect Filtration
The Fluval Siena 332 uses Fluval’s patented Easy-Connect system to route the external filter connections directly through the base of the aquarium.
This eliminates the usual collection of inlet and outlet hoses hanging over the back of the tank. The pipework instead disappears neatly into the cabinet below
Apart from looking considerably tidier, this means the aquarium can sit flush against a wall without needing additional clearance behind it for filter hoses.
Powerful Fluval 07 Series External Filtration
A Fluval 07 Series external canister filter is supplied with the Siena 332, providing high-capacity mechanical, biological and chemical filtration.
Fluval quotes a 2650 LPH pump output for the filtration supplied with the 332L model.
External filtration also leaves more usable space inside the aquarium and provides substantially more room for filter media than a conventional internal filter.
Combined with the Easy-Connect system, it delivers powerful filtration without making the equipment a prominent part of the display.
Twin Plant 4.0 LED Lighting
The Fluval Siena 332L Aquarium includes two high-output Plant 4.0 LED lights.
Designed with planted freshwater aquariums in mind, the lighting provides a broad spectrum with a 7500K colour temperature and can be controlled through the FluvalConnect mobile app.
You can customise the lighting output and create a programmed daily schedule rather than relying on a simple on/off timer.
With two lighting units covering the Siena’s 110 × 55cm footprint, this is a particularly attractive aquarium for anyone planning a planted display or detailed aquascape.
Fluval M Series Heater Included
A Fluval M Series submersible heater is supplied as standard, providing thermostatically controlled heating for tropical setups.
Its slim reflective glass construction helps it blend into the aquarium surroundings, reducing its visual impact within the display.
Together with the hidden Easy-Connect filter pipework, this helps keep visible equipment to a minimum.
Premium Glass Aquarium Construction
The Siena combines substantial glass construction with carefully considered finishing details.
Fluval uses 10mm polished glass panels, black silicone and upper strengthening bars designed to minimise glass flex. Decorative 3M top and bottom edging gives the aquarium a smart furniture-style finish.
The base is slightly elevated and recessed, creating a subtle floating effect above the cabinet.
Two lightweight aluminium-core canopy panels slide independently, making everyday feeding and maintenance easy while allowing the panels to be completely removed when greater access is needed.
55cm Front-to-Back Aquascaping Depth
One of our favourite features of the Siena range is its depth.
The 110 × 55 × 55cm aquarium gives the Siena 332 plenty of front-to-back space for creating a convincing sense of perspective.
Rocks and wood can be positioned at different depths rather than simply arranged across the back of the aquarium, while plants can be divided naturally into foreground, midground and background areas.
The additional 20cm of length compared with the Siena 272 also provides more open swimming room for suitable larger or more active species.
Furniture-Style Siena Cabinet
The matching Siena cabinet is designed as part of the complete aquarium rather than simply being a stand underneath it.
Soft-close hinges provide smooth door operation, while the cabinet feet can be adjusted for height from inside the cabinet, leaving the exterior clean and uncluttered.
Storage features include an inner-door work shelf, wire storage basket and stainless-steel hook, giving you somewhere sensible to keep food and everyday aquarium maintenance equipment.
The cabinet interior matches the exterior finish, while the detail between the doors coordinates with the aquarium edging above.
Available in Three Finishes
The Fluval Siena 332L Aquarium is available in:
Black
Chicago Concrete
White
Each finish combines a coordinated aquarium and cabinet to create a complete furniture-style display.
Suitable For
The Siena 332 is particularly well suited to:
Larger tropical community aquariums
Planted freshwater aquariums
Aquascaping
Suitable larger or more active freshwater fish
Feature aquariums for living rooms and open-plan spaces
Fishkeepers wanting external filtration without visible hoses
Its combination of 110cm length and 55cm depth gives you considerably more freedom with both livestock selection and aquascape design than a shallower aquarium of similar capacity.

Why We Recommend the Fluval Siena 332L
The Fluval Siena 332L Aquarium strikes a particularly nice balance between size and practicality.
At 110cm wide, it provides substantially more swimming room than many medium-sized aquariums without requiring the full 120cm or 150cm footprint of a much larger system. More importantly, Fluval hasn’t achieved the capacity simply by making it tall — the 55cm front-to-back depth gives you genuinely useful space.
The equipment package is equally impressive. External filtration, twin Plant 4.0 LEDs and an M Series heater are included, while the Easy-Connect system hides the filter hoses completely.
Add the thoughtful cabinet design and app-controlled lighting, and the Siena 332 feels like a properly integrated aquarium system rather than a collection of separate components bundled together.
