Key Features
  • THE PERFECT AQUARIUM FOR SMALL SPACES — The TUBE aquarium has cylindrical contouring and a 360-degree view, so you can easily find a space to place and admire your biOrb. The 9.2-gallon tank's size is ideal for tabletop display.
  • DURABLE CONSTRUCTION — biOrb aquariums are made from acrylic, which is 10 times stronger, 50% lighter, and 23% clearer than ordinary glass aquariums. Acrylic is also a good insulator, so you don't lose as much heat as you would with a glass aquarium.
  • FILTRATION SYSTEM IS EASY TO MAINTAIN — All biOrb aquariums have a true 5-stage filtration system including biological, mechanical, chemical, water stabilization and oxygenation that keeps it clean. The filter is conveniently located at the bottom of the aquarium, and the ceramic media surrounding it promotes the growth of beneficial bacteria.
  • VIBRANT, MOOD-ENHANCING LIGHTING — Use the included remote control to select one of the 16 preset colors, fade through the entire spectrum of colors, and control the brightness of the LED lights. You can also set automatic 8-, 10-, 12- or 14-hour day and night cycles for a more natural scene for your aquarium inhabitants. This natural cycle helps cut down on algae blooms, which benefits fish health, water quality, and cuts down on routine maintenance.
  • EVERYTHING YOU NEED TO GET STARTED, JUST ADD DECOR — Includes a 9.2-gallon (35 L) acrylic aquarium with a new flush base plus streamlined features and improved cord management, white LED lighting, a quiet air pump, a low-voltage 12V transformer, filter, air stone, ceramic media, starter water treatments, and instructions. Just add decorations! Also includes a 2-year warranty.

Questions? We've Got You.

Are biOrb aquariums freshwater and saltwater compatible? 

Yes. biOrb aquariums come with everything needed for a freshwater setup. For a saltwater setup, you can adapt the Service Kit by removing the foam. You would then need to source the salt and hydrometer at your local pet store. If a higher-intensity light is needed, there are a few add-ons you could source. We recommend using an 8-gallon or larger biOrb aquarium but always consult your local saltwater aquarium shop for best results. See our tips and tricks for more details.

How often do I need to clean a biOrb Aquarium?

We recommend a simple cleaning routine every 4–6 weeks. biOrb aquariums feature an integrated 5-stage filtration system that keeps water clearer for longer, minimizing maintenance. With our biOrb Service Kits, replacing the filter is quick and mess-free. Just a few minutes of care helps keep your aquarium healthy and beautiful.

Is the TUBE a good choice for beginners?

Yes, the biOrb TUBE is perfect for beginners and hobbyists alike. It comes as a complete kit with everything you need to get started, including a filter, air pump, LED lighting, and water treatments. Its all-in-one design removes the guesswork, making it easy to set up and even easier to enjoy.

What kind of fish can I keep in a TUBE aquarium?

The type and number of fish will depend on the size you choose:

  • TUBE 15 (4 gallons): Ideal for small shrimp, snails, or a single betta.
  • TUBE 30 (8 gallons): Great for a small group of white cloud minnows or tetras.

We always recommend cycling your tank first and checking with your local aquatic specialist to make sure your fish are a good match.

What makes the TUBE different from other biOrb aquariums?

The TUBE stands out with its smooth, elliptical shape, offering a softer, more organic look compared to round styles like the HALO or elliptical forms like the LOOP. Its 360° view means you’ll enjoy every detail of your underwater landscape from any angle, while the elongated silhouette creates a sleek, modern statement.

Each biOrb aquarium shares the same filtration technology, high-quality acrylic build, and easy-care promise—so you can choose the shape that best suits your space and style.

Does the MCR light turn off completely at night?

Not automatically. The MCR timer ends in a soft blue “night mode,” not full darkness. This setting is designed to mimic moonlight and provide a calming nighttime environment for your aquarium. If you prefer complete darkness, simply turn the light off using the remote or inline switch.

Does the MCR timer work with color options?

No, the timer function works with white light only. When you set a timer (8, 10, 12, or 14 hours), your biOrb will follow a natural white-light cycle starting in blue, rising to white, then returning to blue “night mode.” Colored lighting options must be selected and adjusted manually.

Great Looking Tank that works!

"I have been very pleased not only with the look of this tank, but also with the clean filtration system and the ease of care. Easy to set up, bright and clear, great lighting and quiet running. The filter seems to be working well and the biological media seems to have really created a great biofiltration zone. Would definitely recommend."

I had a Biorb Halo

"I had a Biorb Halo for at least a decade and finally decided we needed a new tank. We LOVE the new Tube aquarium. It has so much more room on the bottom to enjoy and appreciate the decorations; no more wasted space at the bottom (or top) of the tank. It is also so much easier to get items in/out of the tank with the much larger opening at the top. I gave the Tube a 5 star rating, but would give Biorb overall 4 stars for two reasons. One, I feel Biorb should give you the option to choose which media you want; the ceramic one or the pearl (instead of having to pay extra for that too). There is no comparison for me, the pearl is the way to go (though I wish it was darker in color), especially with a tank where you can see the acrylic all the way to the bottom of the tank. For us, the ceramic media seemed to scratch the acrylic near the bottom no matter how careful we were when cleaning the tank. Also, it doesn't seem the pearl media will leave the "grit" at the bottom of the tank. Second, there seems to be FAR fewer options for sculptures/decorations/sets than there have been in the past. I'm hoping that there are new ones coming soon!"

Excellent, 5 Stars

"Very satisfied with the Tube 35 Aquarium, my cichilds love it! My previoud Tube 35, that had been gifted to me was roughly three years old and had been moved to multiple different locations, taking on wear and tear over time. It wasn’t until a few days after I had performed a deep clean, I noticed a very small crack in the base, which led to a leak on the bottom of the tank. Thanks to their quality built acyrlic tank, I was able to catch it right away without it turning into a big mess. I temporarily moved the fish into small separate plastic tanks, since they were all I had. I was worried that the new tank wouldn’t arrive on time and that I’d have dead fish on my hands; thanks to their very timely delivery, all of the fish made it into their new home, their support was very helpful, and considerate of the situation. Thanks Biorb!"

Q&A

What is the filled weight of the Tube 9.2 gallon (freshwater)?
Hello Amber. Depending on the decor placed in the aquarium, roughly 70-75 lbs. We hope this helps!
I am interested in purchasing this for my betta fish. How would I put a heater in this with the lid being so snug? Thank you
Hello Tara. We thank you for your review. We do carry a biOrb Heater Pack that is sold separately, https://us.biorb.com/products/45999?_pos=1&_sid=a54b41052&_ss=r The biOrb Heater Pack is designed to be compatible with all biOrb aquarium models, except the HALO 15 (4-gallon). It includes a heater stand with suction cups that allow you to firmly attach the heater onto both curved and flat surfaces of your aquarium. We hope this helps!
How much ceramic media is included?
Hi VJS, All biOrb aquariums come with enough ceramic media to sufficiently cover the bottom of the tank. The TUBE 35 comes with 6 lbs of Ceramic Media. We hope this helps!
