Charming Aquarium Décor: Imitating the real sea urchins, the appealing rainbow ornament turns your tedious fish tank into a lifelike ocean landscape.
Glow Under Extra Lights: The rainbow décor can’t be luminescent in the dark but glows under actinic lighting. Great for brightening and invigorating your plain aquarium.
Stable in Water: Designed with a strong resin base weighing 4.4 oz, it always stands stably in the tank when the rainbow needles swing with the movement of water.
