Fluval Flex Curve Stand
A stand shaped to match the Flex's curve, in three sizes and finishes.
The Curve Stand is Fluval's coordinating base for the Flex range, built with the same rounded front as the aquarium above it rather than a generic rectangular cabinet. It's sold here in three configurations: 57 litre in Black or White, and 123 litre in White. Each includes an integrated shelf inside for filter media, food and the odd bit of tank kit.
Key features
- Curved front panel – follows the aquarium's own lines instead of sitting underneath it as an afterthought.
- Internal shelf – a single shelf for storage or for displaying decorations, built into both sizes.
- Sized to the tank – 57 litre and 123 litre options, matched to the Flex aquarium they're sold to sit under.
- Two finishes on the 57 litre – Black or White, so it can match or contrast with the aquarium trim.

Fluval doesn't publish an empty weight or a maximum load rating for either size of Curve Stand. If floor loading matters in your home – an upstairs room, or an older timber floor – remember water alone weighs 1 kg per litre, so a full 57 litre or 123 litre display carries substrate, rock and glass on top of that; check with a builder before placing either size upstairs on an older floor.
Which stand do I need?
| Your aquarium | Stand to order |
|---|---|
| Flex 57 litre, Black trim | Curve Stand 57L, Black (FLX30) |
| Flex 57 litre, White trim | Curve Stand 57L, White (FLX31) |
| Flex 123 litre | Curve Stand 123L, White (FLX33) |
Fluval also makes a separate Cabinet Stand for the 123 litre Flex, sold on its own page in both Black and White – a squarer, more enclosed design at a different price point. If you want the boxier cabinet look rather than the curved stand, check that listing instead.
What's included
1 x stand, in the size and colour selected, with fitting hardware to assemble it.
Not included
- The aquarium. This is the stand only – the Flex tank, light and filtration are sold separately.
Suitable for, and not suitable for
Suitable for a Flex 57 litre or Flex 123 litre aquarium, matched to size. Not suitable as a stand for a different brand or shape of tank – the curved front is built to the Flex footprint specifically, and it isn't rated for tanks it wasn't designed to carry.
Goes well with
- Fluval Flex aquarium – the tank this stand is built to sit under
- Fluval Flex Cabinet Stand, 123L – the squarer alternative for the 123 litre Flex

Common questions
What's the difference between the Curve Stand and the Cabinet Stand for the 123 litre Flex?
Both are sized for the same aquarium. The Curve Stand keeps the tank's rounded front line; the Cabinet Stand is a squarer, fully enclosed design. They use different fitting hardware and aren't interchangeable.
Is the 123 litre stand available in Black?
Fluval makes a Black 123 litre Curve Stand, but we currently stock the White finish only. Get in touch if you specifically need Black and we can check availability.
Does the stand come assembled?
No, it ships flat-packed with fitting hardware included.
Can I sit a Flex 57L on the 123L stand, or vice versa?
No – each stand is sized to its own aquarium's footprint and weight, and mismatching them isn't a safe fit.
