Marine Sources Fish Isolation Box Double

Marine Sources Fish Isolation Box Double is a hang-on fish isolation box for aquariums, designed to keep a fish separate inside your tank while water still flows freely through it. It has two removable compartments, a folding top cover and a front door, so it suits aquarists who need to separate a fish without setting up a second tank.

• Narrow rectangular openings allow water to flow in and out freely without blockage.
• The bracket hangs on the aquarium and is reinforced for open-frame tanks.
• A folding unit at the top opens and closes the cover with minimal effort.

• Individually packed and ready to use, with no need to re-install.
