Ready to level up your professional aquarium setup? Choosing the right system for housing and displaying fish is vital, as it benefits both the fish and those who care for them. That’s exactly why the new Betta and Livestock Holding Systems were designed: to solve the challenges that hobbyists, breeders, and pet stores face every day.

These systems are made from the same high-quality glass as the UNS Rimless tank lineup. Ultra-clear glass and textured black back panels give users an uninhibited view of their livestock.
The Betta Display System has four 7.08″ (18 cm) tall glass aquariums divided into 8 compartments. This gives you 32 spaces to safely act as an aquarium for betta fish. The Livestock System has three 9.84″ (25 cm) tall aquariums with adjustable baffles, making it easy to change the setup for different species.
Our fish holding systems can operate as either freshwater or saltwater aquariums, meaning more efficiency in the same space. One tank can act as a clownfish holding system, while another can hold Gobies, for example. Users can care for livestock with different needs all in one system. The shared plumbing and large sump increase the water volume in the system as well, improving fish health and keeping water quality high.

We’ve seen fish store display tanks rust, wobble, or fail under heavy use. These commercial fish holding systems are designed with rust-resistant aluminum. They have a wider base and use strong materials identical to our Reef Systems and other Holding System stands. Your setup stays secure and stable for the long haul, even in humid conditions or when fully stocked.
Maintenance can eat up valuable time. That’s why every tank has Durso-style drains for quiet operation and easy flow into the glass sump below. The sump has four sections for customizable filtration. This lets you easily mix mechanical, biological, and chemical methods to your system’s needs.

Instead of siphoning and buckets, each tank features a bottom drain with ball valves for quicker and more thorough draining. You can flush tanks individually, targeting the specific tank that is being worked on, and drain directly into a hose connection for faster, cleaner water changes—and more time enjoying your fish.

The sump has a backwash function in its return plumbing. This feature helps you stir up and remove debris quickly, keeping the sump clean with little effort. Circulation is managed by one return pump, and each display tank has adjustable ball valves, ensuring each tank gets the flow it needs.

A built-in refill valve lets you bag fish directly from the system. This reduces stress for the fish and makes daily operations easier, especially when used as a retail aquarium system.
The all-new Ultum Nature Systems Betta Holding System and Livestock Holding System make the perfect displays for any space. We designed this system from the ground up to streamline your pet store fish display or home fish systems, all while maintaining the signature UNS aesthetic.
