I should have waited to review until my tank was all set up but I just can't wait. I will 1000% order again. The color is absolutely perfect and matches my river rock substrate perfectly and I believe it will blend in beautifully. The only challenge will be deciding which one to get next because the possibilities seems endless with how you could arrange these! It's often hard for me to find hides large enough for my freshwater crayfish but I am thrilled to have found this shop! Thank you so much for making it easy to order, great communication, good prices, packaged with care- I will be back for more!

I cannot say enough good things about this product! It is always hard to tell the exact scale of things from images, but this print is thicker than I was expecting so it is nice and sturdy. It will certainly hold up and is easy to work with. My tarantula loves it! It makes me wish that I had more spiders to buy these for just to support the maker of such a great thing!

The quality of the cave is superb, looking exactly like the pictures. The seller responded very quickly to any queries and provided excellent clarification. The only downside was that the package couldn't be tracked. Otherwise, however, complete satisfaction and excellent service. Highly recommended 👍🏼

Payton
Absolutely love this hide for my axolotl tank, only regret is not going even bigger but this size works perfect for my current tank set up. The hole is perfect size for the axolotls to be able to go in and out of and provides them a nice area to hide.
Magnus
Love it! Bought a different one before and put one in each front corner of my aquarium. Its really sturdy and over all really nice material and texture. Rough makes it blend in in a nice way.

Looks great! Added to a new tank. Can’t wait to see shrimp in it once the tank cycles.
Kass
