Eshopps' life-sized floating Lionfish aquarium ornaments attach quickly to your aquarium bottom or side with the included suction cup and invisible tether line. An internal air bladder keeps the Lionfish floating realistically. Your aquarium water currents cause the stunning Lionfish replica to behave very similarly to a live Lionfish - your aquarium observers will be amazed at the Lionfish's realistic swerving, hovering, and swaying. The Soft, flexible polyester material of the Lionfish will not harm your live fish. Choose Brown for a more realistic look, or Pink for a sassy splash of color. Lionfish decorations measure 3x2x5, and include 1.5in suction cup and 17in line.
