Good concept, but my shrimp are a mat too big to get inside. I gave 4 stars because of this. My suggestion, make the holes a little bigger. (Just a little) and maybe wider holes on the bottom so I don’t have to cut the bottom off, when I need to get one out that’s stuck. My guppy fry actually love this thing more than anything else. Gives them an additions hide out, to survive hungry parents, and they’re always hungry, and there’s always baby fish (fry) Thanks.

As others have said on the one star reviews, there's something going on with this stuff. I had a perfectly healthy tank, with around 30 shrimp that were thriving. I followed the directions of cleaning these rocks before using them, and dropped on into the tank. Overnight my tank turned into a toilet water brown color and all of my shrimp were dead!!! Easily over $150 worth of effort down the drain. I drained all the water out and out in fresh, hoping I don't have to ditch the whole tank or substrate. What a scam!!! Stay away, this stuff likely came from Chinaland.
