About us
Where it started
Hollow began in 2022 in a small Parisian apartment with a single 3D printer and a simple vision: aquarium decor could offer more.
From the beginning, the goal was to create caves that felt more natural, more sculptural, and more connected to the aquascape itself.
More than three years ago, the first pieces were simple, boxy, and unnatural. Over time, through constant refining, testing, and observation, that vision evolved into a design language of its own. Forms shaped to feel organic, balanced, and truly at home in a real setup.
Our philosophy
We believe aquarium caves should never feel like artificial objects placed inside a tank. They should blend into the scape, support the composition, and feel as though they have always belonged there.
That belief shapes every design decision we make. Our pieces are created not only to serve a purpose for our little creatures, but also to bring realism, and visual harmony to any setup.
How each piece is made
Every Hollow cave starts with design.
Each model is carefully developed to achieve the right balance of shape, texture, and realism. The goal is always the same: to create a piece that feels natural, solid, and visually convincing, while remaining easy to clean and practical to maintain in planted tanks, aquascapes, and terrariums.
These are not mass-market decorations pulled from a generic catalog. They are original 3D printed designs shaped through hours of refinement, with close attention paid to detail, finish, and how each piece will actually look once placed inside a real setup.
