A calm little world for your betta.
Cupang designs aesthetic betta fish tanks — hand-blown glass spheres suspended on sculptural ironwork, quiet beautiful objects you can customize with your own artwork.
Handcrafted acrylic
Each spherical bowl is shaped and finished by hand from crystal-clear acrylic — lighter, shatter-resistant, and just as luminous as glass.
Betta-friendly
Designed with the right volume, opening, and stillness your betta actually needs.
Custom artwork
Add your own pattern, koi motif, or short engraving to make it truly yours.
