Easy to set up and style

Simply position the hide in your terrarium and surround it with substrate, moss, bark, or plants. That's it. In just a few simple steps, it creates a mesmerizing underground world that adds depth, shelter, and a natural look to your setup.

Dark and secure retreat

The enclosed interior and narrow entrance create a private resting spot for reptiles and other animals that prefer darkness, security, and minimal disturbance.

It creates natural hiding spots, offers protection from light and reduces stress. Because the hide sits directly against the glass, you’ll be able to see and enjoy your pet more often.

Sturdy and built to last

Built with a strong structure and thick walls. Crafted from biodegradable, biosourced, and recyclable PLA, the cave can also be placed under a basking light at temperatures up to 50°C / 122°F.

This shrimp hide has worked great for my aquarium. It provides a safe, cozy space for my shrimp and fits seamlessly into a planted tank. The quality is excellent, and it doesn’t look out of place at all—highly recommend.

This seller is so nice to work with and is very communicative! They were able to make the product a customer size that works for my leopard geckos tank. It looks awesome and my leo immediately spent like two days under the shelf! It’s perfect!

Some of my largest neocaridina can't fit but many can. I already see many shrimp in there and I hope it helps with their breeding

Frequently Asked Questions

About the caves

No. Every piece is made from aquarium-safe PLA that is biodegradable, biosourced, and fully inert. It will not affect your pH, hardness, or any other water parameter. Safe for fish, shrimp and marine aquariums.
Yes. Our pieces are suitable for terrariums and reptile setups as well as aquariums. Check the individual product page for compatibility details, especially dimensions, if your animal fits through the entrance comfortably, you are good to go! The rest is design preference. Disclaimer: Do not put it directly near high heat (Up to 50°C+/122°F+)
The large openings are intentional, so most caves are easy to clean with a standard aquascaping tool kit. A magnetic cleaner and a soft brush or toothbrush are highly recommended for the surrounding glass. We use the Chihiros Mini on all of our cave tanks. A regular hose is used to clean debris inside the cave.
The first step is to check the dimensions on the individual product page, below "Add to cart". If your animal can comfortably fit through the entrance, you are good to go. Beyond that, the choice is mostly visual: most caves can work in most tanks. A smaller cave works well as a subtle detail or accent piece, while a larger one creates a stronger focal point in the scape. Do not overthink it, our caves are designed to blend naturally into the setup, regardless of the style of your tank. That is exactly what they are made to do.
