Love these caves!
These caves are an excellent way to add privacy and separation for fish that need a little quiet time for themselves. Easily to install and the size was expected. My corydora’s love the two we have installed in their tank.

Good
Cute! My betta loves it! Doesn’t float and is in great shape even with months of being in tank and despite moving it around a lot due to rearrangements I’ve done to the tank.

Perfect!
Such a perfect addition to my tank. It’s a perfect size and my fish and shrimp love it. It was such an easy installation, all I had to do was move the soil and bury it. That’s it. Definitely worth the money and It’s so much fun seeing my aquatic animals inside of it.

Works great but messy
This is great for loaches and suckers but definitely gets dirty and hard to remove once in place

A great cave for the fish
My fish and shrimp love this thing and I think it’s great that I can watch them. I haven’t had a problem in the world with this product.

Good quality. Thick material.
Great little place for my bottom dwellers to hang out in. Allows us to see what they are up to.

A nice little apartment.
A bit smaller cave than I pictured, but my shrimp and minnows enjoy having a place to chill, not so much my koi, gold fish, and placo. But for the few bucks, it is well worth it to give my shrimp and minnows a place to nap.

High quality! Perfect playground for Cory Catfish!
After having established a tank over a couple months, I noticed my few Cory catfish weren’t quite as playful or energetic as they should be (even for their laid back personalities) and I asked my LFS if it was worth adding sand to the gravel substrate, or a partial area. It’s an ongoing debate as I now know whether Cory’s should or shouldn’t have sand to mimick their natural habitats to make their little lives happier. This product was a PERFECT addition to my tank even though the LSF store said they’d be fine with gravel…I looked at similar products but the reviews speak for themselves on this one! Very durable with some weight, smooth edges and overall very high quality cave feature. Although it took some careful rearranging and cleaning of my tank, getting the premium sand rinsed in the sink and scooped into this cave unit ahead of time, I was able to lower it carefully into the existing tank without making a giant sand mess. If you’re starting from scratch this would be super easy to add before water! The pic only shows one of my few Corys, but they all found the sandbox cave within 24 hours and there’s 100% noticeable difference in their more playful behavior. Our bristlenose sucker, snail, and shrimp all take turns in and out of this unit too!
