Unlike live aquarium flora, our artificial plastic plants don’t require specialized lighting, and don’t need to be pruned into shape or size! Each plant within this 18 piece bundle features a realistic appearance and a gentle touch! This bundle includes (12) 4” plants and (6) 6” plants. Safe and Durable Materials: Our aquarium plants are inspected with your pet’s safety in mind. All materials used are safe for both freshwater and saltwater aquariums. They also feature a sturdy ceramic base that keeps them grounded in your fish tank. Weighted Base for Secure Mounting: Each artificial plant features a weighted ceramic base, ensuring that they’ll stay in place. This eliminates the worry of constantly having to adjust their placement within your fish tank. Super Simple to Clean: Before placing into your tank, or as you as perform regular cleaning and maintenance, simply wipe down and rinse off plants with warm water. Never use soap, as the residual soap particles can harm your fish.
