Frequently Asked Questions

Q: Is the resin hiding cave safe for fish and aquatic animals?

Q: What size hiding cave should I choose for my aquarium?

A: The Small (8 × 7 × 6 cm) is ideal for nano tanks or smaller aquariums housing petite fish or shrimp. The Large (12 × 10 × 9 cm) works best in standard or larger tanks and accommodates bigger cave-dwelling species like cichlids or larger betta fish.

Q: How do I clean and maintain the aquarium cave decoration?

A: To maintain its natural-looking appearance, gently scrub the cave with a soft brush and warm water during regular tank cleanings. Avoid harsh chemical cleaners or soaps, as residue could affect water quality. The durable resin material is designed to retain its color and texture over extended use.

Q: Can I use this cave in both freshwater and saltwater aquariums?

A: This resin cave decoration is primarily designed and recommended for freshwater and planted aquarium setups. If you plan to use it in a saltwater tank, ensure it is fully cured and rinse thoroughly before placing — always monitor water parameters after adding any new decoration.
