What to Compare Before Buying
- Size: Compare the stated 2.3" D x 4.3" size with the space you want to fill in the aquarium.
- Lighting: The glow effect depends on actinic lighting, so check whether your tank lighting can create that look.
- Placement: The resin base is meant to keep the ornament on the bottom of the tank, so confirm that this suits your layout.
- Look: The ornament is intended to add colour and a sea-life style appearance to the tank.
Before You Decide
Confirm the aquarium size, the rainbow finish and the lighting you plan to use before choosing this ornament. It is best considered when you want a fixed decorative piece with a glow effect under actinic light rather than a decoration that glows in darkness on its own.
