Small, but they do the trick!
While these are a bit smaller than I was expecting (the one in my hand is the largest one), these rocks are nice! Great shapes for building up a rock wall in my shrimp tank! I will be getting more, maybe some larger ones from somewhere else, but these will definitely be put to good use! None of them came broken, but you will definitely need to rinse these off as there is a lot of rock dust on them, as you can see at the bottom of my bucket. (Itâs a 2 gallon bucket BTW, not a 5 gallon, and the larger rocks in the pictures of my tank are from a different order of four larger rocks)These really helped make my tank beautiful!

Not for aquariums
Awful. First I ordered red stone and got black. Second, even after a few days of soaking only half of the stones have kind of sunk. The rest are floating. These are for indoor or outdoor gardens and not for aquariums. Most of the rock that was sent to me are unusable for my needs.

Good buy
These are perfect for my shrimp tank project. They werent too big and werent too small; just perfect.

Perfect for any tank
I really like these rocks! They are a perfect addition to your tank. My shrimp love hiding in these and because there are many pieces, you can build it up however you want. I do wish there was a little variation in shape, but I understand that these are natural rocks so I cannot complain. The color is nice. My shrimp and snails do a great job of cleaning them up. I only have to occasionally do minor cleaning on them!

Not accurate size. Not even close
Yes they are pumice stone. No they are nowhere near 1-2 inches in size. More like 1/2-3/4 inch size. Not worth what you pay.

Excellent rocks
These rocks were the perfect size. I split the pack amongst 5 different tanks. This one on the bottom right has an Anubias glued to it. They rinsed off easily and did not leach any color into the waters. The fish and shrimp seem to enjoy it. I will be purchasing again in the future
