I bought 2 of the small caves for my African cichlid tank and they love them! I thought only the smaller fish would use them but, surprisingly many of my larger fish (4-5 inches) enjoy them as well. Great purchase!
There are 3 sizes, I order a small one ,but do believe they sent me a medium one instead, But still work
Haven't gotten shrimps or snails to test it out, buy it looks good and matches the feel of the tank setup.
I was surprised by how nice it is. Good quality and good price. Perfect l addition to my 30 gallon fish tank.
Love it. Very nicely made and no sharp edges. Looks great in my molly and Dwarf gourami tank.
