About Tetra

Tetra has a simple mission: show the world that keeping aquatic pets is fun, fascinating, and easier than you might think! The title of largest global manufacturer of ornamental fish foods doesn't come easy, and their decades of experience are evident across OnBuy's Tetra fish shop!

Masters of the home aquarium, you’ll find everything you need to create or maintain your own fish palace! A Tetra aquarium coupled with some Tetra aquarium accessories is certainly a great place to start – you’ll find Tetra filters, Tetra AquaSafe solutions to keep conditions perfect, while the Tetra aquarium decorations will add a lovely touch.

Now just because your finned-friends live outside doesn’t mean they should get any less love! OnBuy’s collection of Tetra pond items also keeps their water safe– Tetra Crystal Water and Tetra Water Stabiliser put you firmly in control of the chemical composition of their pond. Tetra AlgoFin and Tetra AlgoRem are ready to act against algae and weeds, while Tetra Medifin helps to heal your scaly friends if they feel under the weather.

If you’re hoping to find fish food you’ve certainly come to the right place! OnBuy’s feast of Tetra fish food caters for all species, whether they live indoors or outdoors; the TetraPro line is crafted specifically for different aquarium fish, whereas the Tetra Fresh range is perfect for all aquarium residents. Don’t fear though – the pond-dwellers can enjoy Tetra Pond Pellets, Tetra Pond Flakes or Tetra Pond Sticks too, so everyone can join in!
