Cute and convenient!
Works great! My shrimp and snails and coryâs love this! And itâs cute watching them shuffle about! Very sturdy material as well and large enough for even my betta to swim in alongside all the other critters and have plenty of room!

Best way to watch…
I Iove watching my little Panda Corydora’s & Shrimp explore the cave I bought. It’s their little sanctuary that makes my office a peaceful place to work.The quality of these caves is amazing, definitely exceeded expectations. They are easy to add to the tank, the size is perfect for my smaller fish! And it makes the tank that much more functional. I like my fish to have a place to hide and feel safe, but I also like to watch them…not in a voyeuristic kinda way, get your head outta the gutter.These are totally worth the money and make the money I spent on fish that like to hide so much more worth it!

Smaller than it appears
It is way smaller than it looks in the pictures. My yoyo loaches (3″) can barely fit. Pretty sturdy tho. Ish it was twice the size.

High quality! Perfect playground for Cory Catfish!
After having established a tank over a couple months, I noticed my few Cory catfish werenât 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. Itâs an ongoing debate as I now know whether Coryâs should or shouldnât 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 theyâd be fine with gravelâ¦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 youâre 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 thereâs 100% noticeable difference in their more playful behavior. Our bristlenose sucker, snail, and shrimp all take turns in and out of this unit too!

Awesome
I love this little cave, so do my shrimps and betta. Itâs so great to have something like this in a tank because it creates great hiding places but also makes the tank more dimensional. Love it.

Too small for my tank
Why did you pick this product vs others?:Its too small for my aquarium. The plecos move it around and turn it upside down. Sadly not for my tank
