Awesome purchase for an aquarium
This is such a great product. Excellent price and immediately ready to use. I got these for some of my soon-to-be shrimp to give them a little hiding spot from the fish I’m putting in my aquarium. It looks great. Doesn’t float or move once setting it in the gravel. Totally recommend.

Perfect in our 30-gallon aquarium
This has worked perfectly in our aquarium! It took a little work to get it under the gravel since we already had water in the aquarium, but we made it work. It's perfect for our bottom feeders and other fish as well. I would definitely recommend! It seemed very well made, so no problems with the quality. I got a great buy for a great price!

Kuhl-est kuhli cave
This is the kuhl-est cave for my kuhli loaches. It's well made, sturdy, and a great size for my aquarium. My loaches love to go into the cave and sleep (or cause chaos, it's a 50/50 chance). Love being able to see them as they burrow and play.

As described
It works as intended. It's neat to see the fish in there, but wish they liked it more than I thought they would. Might be better for frogs or shrimp.

Good
A little smaller than I thought might need to order another one.

Game changer!
Bought with my new 2.5 gallon tank and changed the whole look of the tank. 100% what i pictured in my head. Will take a good amount of space in a 2.5 gallon tank so decorate accordingly

Big and smooth
I love it and tried to block my betta fish but was unsuccessful. My betta is chill but i want a nice area for just the catfish so im glad my betta is rarely interested in going down there. My shrimp molted and also hides there. Its a nice size. Sand gets in it but that's ok.
