Frequently Asked Questions
Are all aquarium ornaments safe for fish?

How do I clean new aquarium ornaments?
Before placing a new ornament in your tank, rinse it thoroughly under cool, running tap water. This helps remove any dust or residue from the manufacturing process. Avoid using soaps or detergents, as these can be toxic to fish.

How many ornaments should I put in my aquarium?
The number of ornaments depends on the size of your tank and the swimming space needed for your fish. While decorations add interest and hiding spots, avoid overcrowding the tank. Ensure there is ample room for your fish to swim freely.
