Printed Reef Mushroom Cage (2", Orange)
This mushroom cage is perfect for protecting mushrooms in your tank. It features a honeycomb design, with a 0.5" hole on the bottom that allows you to use a frag plug for the mushroom to self attach.
Once you close the lid the mushroom will be protected and you will no longer have to worry about it floating away. After some time, you will now have a mushroom that has nicely attached itself to the frag plug.
