👍 Pros

  • Genuine design object — the acrylic sphere is a talking point
  • 5-stage filtration and a remote-controlled colour LED included
  • Acrylic is far lighter and more impact-resistant than glass
  • Simple, self-contained system that's easy to site anywhere

👎 Cons

  • Curved acrylic scratches more easily than glass and distorts the view slightly
  • The spherical shape is hard to aquascape naturally and limits swimming space
  • Proprietary media and cartridges add to running cost
  • Best kept lightly stocked — not a community tank

A tank you buy with your eyes

The biOrb Classic 30 is unapologetically a design aquarium. The clear acrylic sphere, the hidden air-driven 5-stage filter and the remote colour LED make it a striking centrepiece for a home or office — and its acrylic build is light and won’t shatter like glass. If someone wants “a beautiful fish tank” more than “a fishkeeping hobby”, this is often the one that makes them happy.

The honest trade-offs

That styling comes with real compromises. The curved acrylic scratches more easily than glass and bends the view a little; the spherical shape is hard to aquascape naturally and limits swimming room; and the proprietary cartridges add to running cost. Keep it lightly stocked and it thrives — overstock it and the small, rounded volume gets unstable.

If flexibility matters more

Prefer to actually aquascape and keep a small community? A rectangular tank like the Fluval Flex 15 or the value Aqueon 20 gives you far more freedom for similar money. Choose the biOrb when the look is the point.

⚖️ The bottom line

Buy it for the design, not the aquascaping. As a low-fuss, sculptural centrepiece it's lovely; for a flexible planted or community tank, a glass box gives you far more.

biOrb Classic 30 — frequently asked questions

Is the biOrb a good aquarium or just decoration?

It's a real, working aquarium — but one designed around looks and simplicity. If your priority is a sculptural centrepiece with minimal fuss, it's excellent. If you want to aquascape or keep a busy community, a rectangular glass tank suits far better.

What can I keep in a biOrb Classic 30?

Keep it lightly stocked: a small group of hardy fish or a shrimp/snail setup. The 30 L volume and rounded shape don't suit large or active schooling fish.

Does the acrylic scratch?

Yes — acrylic is softer than glass, so clean it with a soft biOrb-safe pad and avoid gritty cloths. In return it's much lighter and won't shatter.
