MacroAlgae Floating Island

[Vorteil]

This macroalgae started at the bottom of the tank. Every so often it would start to get air bubbles in it. Not sure why or why some would get air bubbles and others not. Eventually I got tired of poking the bubbles out. It floated to the top and I just left it. It looks different from others but this is the same Supershrimp macroalgae I purchased years ago.
