ONE BAYJF Aquarium Acclimation Box, Orange Acrylic with Adjustable Partition

ONE BAYJF is an acrylic aquarium acclimation and isolation box for temporary fish quarantine and shelter in aquariums of 30 gallons (113.6 L) or more, made from approximately 0.217-inch (5.51 mm) optical-grade acrylic.

• Ready to use with no assembly — hang it directly on the aquarium edge.
• Two hooks fit frames up to 17 mm (0.67 in) thick and are also suitable for rimless tanks.
• A detachable partition adjusts the box to one or two isolation spaces.
• 0.1-inch (2.54 mm) slits support unobstructed water flow, while a 0.14-inch (3.56 mm) bottom widening helps keep waste and food residue from dirtying the box.
• A 4.2 x 2.4-inch (10.67 x 6.10 cm) feeding opening lets you feed fish without disturbing them.

When a fish needs temporary separation for isolation, quarantine or domestication, a box inside the aquarium provides a dedicated space without requiring an external container. ONE BAYJF is made for hanging aquarium use, with applications that include saltwater fish and reef coral quarantine. Its product title also identifies it for external hydroponic plant breeding. The aquarium capacity guidance is 30 gallons or more, making tank size an important fit point when choosing where to use it.

How does the ONE BAYJF box attach to an aquarium?

It hangs from the aquarium edge using two hooks, so it is ready for use without assembly. The hooks accommodate frame thicknesses up to 17 mm (0.67 in) and are also suitable for rimless fish tanks. The box measures 9.45 x 6.89 x 8.27 inches (24.00 x 17.50 x 21.01 cm), giving you the overall dimensions to compare with the available space inside your aquarium.

• Hanging design places the box directly at the tank edge.
• Measure the intended aquarium space against the box’s overall dimensions before use.

Can the box create separate spaces, and how does water move through it?

Yes. A detachable partition lets you configure one or two isolation spaces. Slits around the box are designed to keep water flow unobstructed, and the bottom has a widening intended to reduce food residue and fish waste dirtying the box. These design details support its use as a temporary aquarium space for isolation, quarantine and domestication.

• Remove or position the partition to choose between one and two spaces.
• The bottom widening helps limit the buildup of food residue and fish waste inside the box.

What material is the ONE BAYJF acclimation box made from?

It is made from transparent, optical-grade acrylic with an orange color accent. The clear material allows you to observe activity inside the box, while the edges are smooth to help protect fish from injury while swimming. The acrylic is described as having no phosphate (PO4) leaching and as suitable for long-term use in freshwater or saltwater.

• Transparent acrylic provides a clear view into the box.
• Smooth edges are designed to reduce the risk of fish injury while swimming.
• The material is intended for freshwater and saltwater use.

How can fish be fed while they are inside?

A rectangular opening at the top measures 4.2 x 2.4 inches (10.67 x 6.10 cm), allowing you to feed fish without disturbing them. The opening is designed to make feeding possible during quarantine and to help relieve anxiety during that process. Its placement at the top means feeding can take place while the box remains hanging in the aquarium.

• Top-access feeding opening is rectangular.
• Feeding through the opening avoids disturbing the fish, as intended by the design.

This box is suited to aquarium keepers who need a temporary hanging space for fish isolation, quarantine or domestication, including saltwater fish and reef coral quarantine applications. It is intended for aquariums of 30 gallons or more and also has an identified external hydroponic plant breeding application. Its hanging hooks, adjustable partition and transparent acrylic construction define a practical fit for temporary aquarium separation.
