1 Premium & Lifelike 2 Enjoyable DIY

Is this cave safe for Betta fish? Will the edges tear their delicate fins?

It is 100% safe for Betta fish. The XuanFain hideout is designed with perfectly hand-polished interior edges and smooth tunnel openings to ensure there are no sharp burrs. Betta’s flowing fins will not get snagged or torn. Ideal stress-free retreat.

Will this resin log alter the pH or hardness of my aquarium water? Does it release tannins?

It won’t affect water chemistry. It’s crafted from premium, chemically inert & BPA-free resin. Unlike real driftwood, it will not release tannins (which cause yellow) or alter the pH/hardness. It is perfectly safe for all freshwater/saltwater tanks.

Does this hideout float? Do I need to soak or boil it before putting it in my fish tank?

It sinks instantly; no boiling needed. Because the XuanFain cave is made of dense, weighted resin, it goes straight to the bottom without needing rocks to hold it down. Just rinse with warm water before use. Avoid boiling to protect the paint finish.

What is the actual size of the tunnel? Will a juvenile axolotl, pleco, or dwarf cichlid fit inside?

The overall dimensions are 5.1” L x 2” W x 2.7” H. The tunnel is comfortably sized for small to medium aquatic pets like Bettas, Tetras, Ghost Shrimp, Corydoras, and Dwarf Cichlids. Great for juvenile axolotls but snug for adults.

Can I use this L-shaped log in a dry terrarium for my leopard gecko or frog?

Absolutely! While designed for aquariums, the hyper-realistic bark texture and sturdy L-shape make it an excellent dry hideout for reptiles and amphibians. It works perfectly in terrariums for leopard geckos, tree frogs, and small spiders.
