Frequently Asked Questions

Q: Is this aquarium cave shelter safe for shrimp and fish?

A: Yes! This cave is made from water-stable 3D printed materials with no high-concern chemicals, making it completely safe for shrimp, nano fish, and other sensitive aquatic species. The smooth surfaces prevent injury, and the materials do not leach harmful substances into the water.

Q: What size aquarium cave should I choose — S or L?

A: The Small (S) size (7×6.5×5 cm) is ideal for nano tanks, dwarf shrimp, and very small fish. The Large (L) size (10×9.5×7 cm) suits medium-sized community tanks and slightly larger fish or breeding shrimp colonies that need more room to hide and explore.

Q: How do I attach and clean the fish shrimp shelter?

A: The shelter comes with a suction cup for secure, repositionable attachment anywhere on your tank glass or substrate. To clean, simply remove it during a water change and rinse under running water — the smooth, corner-free surfaces make maintenance quick and easy.

Q: Can this cave decoration be used in both freshwater and saltwater tanks?

A: This cave is primarily designed and tested for freshwater aquariums, particularly shrimp and nano fish setups. While the 3D printed material is water-stable, we recommend using it in freshwater environments for best results.
