Clear Horizontal Isolation Box for Aquarium Fish

The clear sides let you observe the separate compartment while the horizontal profile takes up relatively little tank height. The box measures about 4.92 inches long and 2.76 inches in both other directions. Allow access above the lid.

Polystyrene plastic. Approx. 4.92 × 2.76 × 2.76 in (12.5 × 7 × 7 cm). one isolation box.

Measure the clear space above the substrate and around the filter intake before choosing a position. Try the footprint in more than one part of the tank so fish can still swim past on either side. Check that you can reach the item from above for routine cleaning without disturbing the rest of the arrangement.
