The Octo Pen™ is great for mushrooms and other corals you want to isolate from the rest of your tank. Fabricated out of 1/8″ acrylic, available in clear or black. The Octo Pen™ sits on the bottom of your tank and the 1/4″ slots on all four sides allow for flow from multiple angles.
Size shown is 9″ x 9″ x 5″, but we can custom make them any size!
Most of my products are made to order and BY HAND! Please allow a week for fabrication time (longer for Octo Lids™) Shipping prices listed are to the contiguous U.S. Please contact us if you live elsewhere and want a shipping quote.
