## Customer Reviews

### ⭐⭐⭐⭐⭐ betta approved, smooth and natural feel
*by A***M on 26 May 2025*

This is one of my betta’s favourite spots in the tank. The openings are big enough for him to swim through comfortably, and the texture is smooth, no sharp edges at all. Looks way better than most plastic hideouts.Blends well with natural decor and doesn’t float, even in a low flow tank. Great for shrimp or small fish too.✔ Pros:• Safe for fins and soft bodies• Solid weight, stays in place• No paint chipping or weird smells• Looks realistic in planted tanks❌ Cons:• Only comes in one size• Can trap food if not cleaned underTip: Tilt it slightly to avoid trapping uneaten food, and rinse it monthly during water changes.

### ⭐⭐⭐⭐⭐ Love these caves.
*by L***S on 11 September 2024*

The media could not be loaded. We love them and so do my critters. Absolutely brilliant. Good size. I’ve got 4 into a 30x30x30 tank so if yours is bigger you’ll be able to get a good few in. All my crabs and lizards enjoy the caves. Not so much the tee frogs but I’m hoping the crabs and lizards will use them to lay eggs which will make removing them from the terrarium very easy.Final thoughts!Money well spent. You can never have too many caves.

### ⭐⭐⭐⭐ Looks Great!
*by H***0 on 28 April 2025*

Look great but the top one keeps falling off hence the 4 stars.
