Aquarium Ceramic Pot Shrimp Spawning Cave Breed Shelter Ornament, 2-Pack

I like them! They look cute, I have shrimp and they enjoy grazing on it and my betta seems to enjoy swimming in them :)

Still a bit larger than I had hoped. Great material, arrived in great condition. I originally wanted the two for my shrimp tank but they take up a lot of space (even if they're buried.) So I switched some of my fish tank decorations and Nubi (short for Anubis) my Betta fish received one of them instead. He likes to go in and out of it but he prefers his tree log. It looks nice in his 2.7 gallon but if it were smaller I'd be very happy. I still might remove it, depending on how my my Betta uses it. For a 10 gallon they'd be great but even if I used them in my 5.5 gallon, I feel like I'd only be able to use one, without it looking too crowded. If you want it as the centerpiece for a smaller tank, then it could work. But I wouldn't recommend putting too much more in your tank if that's the case.
