Because the caves have an open bottom, you can push them into the substrate as far as you want to make the caves larger or smaller. This allows cave dwellers to arrange the substrate inside the cave the way they want which is a normal part of the breeding process. For my kribensis, I like to push them almost all the way down so that just a tiny hole is left open. The female krib will pick the cave and then rearrange the gravel to make the opening just perfect for her. This gives her a sense of safety so she will breed and care for the eggs and fry.
I've been looking for a dark colored cave that looked attractive in my planted tanks for a long time, and this cave is perfect. I started out with 3 caves and just bought 3 more. No more ugly clay pots! They look great in the tank and don't detract from the beautiful colors of the fish.
UPDATE: My Pelvicachromis clearly love these caves! One pair mated and have successfully raised the fry. They're about 3/4" long now. The other pair have had two sets of fry, but aren't as good at parenting so they've lost both sets. However, they're trying for their third set of fry so maybe they'll do better at protecting them as they gain experience.
Even though I still have other caves in the tanks for my Pelvicachromis fish to use, they most definitely prefer these caves. I'm not going to bother buying any other kind of cave from now on. These caves are a definite winner! Just bought 5 more for a 90g tank I'm converting over to a planted tank! I'll probably get even more for that tank over time.I bought the log. And... it's okay. I think that it's ugly and that the interior of the log should be textured instead of smooth. I thought this was supposed to be shrimp decor. It's as good as any other aquarium ornament out there. My giant blob of java moss has consumed it so at least I can't see it. I hope my shrimp like it because it was expensive.
Nothin' special here.

Made out of nice ceramic. When you put it in the water it becomes a bit darker of a grey. my 2 smaller gourmies love it. I think I've seen the african leaf fish from Petsmart swim in it too. I might by another one of these if my tank needs more shelters.Want Fluval Ceramic Shrimp Decor Aquarium Ornament Discount?
I bought this for my cherry shrimp but they don't seem to go in it or near it. It may be my batch of shrimp but it was good quality.
