Shrimp love it

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.

Being transparent, I've never used this before. It says good for shrimp and also helps condition their aquarium water. So giving it a shot. So far so good. Its easy to add to tank. You get a nice portion for a good price!

Clear directions for acclimating and packaged well. All shrimp arrived alive and I have had them for about a week. All are healthy, no diseases or parasites. The shrimp look healthy with a variety of color and size. They fit in great with my other shrimp. I definitely recommend this seller.

Thought I was doing a good thing for my shrimp and snails, and the white rocks looked so nice against the dark substrate in the tank. I rinsed the dust (so much dust!), soaked the rocks, and rinsed again before adding them to my 42 gal tank. My water parameters were way off 3 days later. My shrimp died before I caught it and my fish were lethargic and flashing. Took all but the tiniest of the rocks out, half water change, pulled every trick I know to balance water parameters quickly and got things back to normal. DO NOT ADD THE WHOLE BAG TO YOUR TANK. It's a tiny little bag, but the high mineral content will mess things up. Now I'm afraid to put any more of these rocks in my tank!

I have a shrimp tank and the block has lasted 2 months so far so they are very durable and and good value. They are about the size of a gravel rock and are white.

Good substitute for cuttlebone in aquariums with crustaceans.
