  • Perfect!
Color: Black
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.

  • Good
Color: Black
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.

  • Cute and convenient!
Color: Black
Works great! My shrimp and snails and cory’s love this! And it’s 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!

  • Great hide for small fish
Color: White
A little smaller than I thought it would be but my catfish fits in and uses it. Does not try to float up even if it's not buried. Would recommend for small or young fish. Easy to see fish inside

  • Love these caves!
Color: Black
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.

  • Works for my Betta
Color: White
It took him a while to decide it was safe to go down there (a few days), but now he goes in and out every now and then. He doesn't hang out for long, but it's nice to give him another option to explore in his tank.

  • Cory catfish love love this
Color: Black
When I open the box I thought what a waste of money for this small hideout. Once I placed in the tank. Which I added after it was filled with water. I drop this in where I want it. Sink nicely all I did was push it alittle closer to the glass. About fifteen minutes later my four Cory catfishes was swimming in and out. Laying down. Perfect hideout. ... show more
