SapphrGlo Huge Glow Stones-Glow in Dark Rocks Large-Decorative Rocks for Beta Fish Aquariums-Garden Glow Rocks River Rocks-Beta Fish Decor Fish Tank Decorations-Glow Pebbles Green (24 pcs)

I was confused whether to get the blue or the green rocks. I did get the blue gems. So glad I did, it looks awesome in my fish tank. Matches the colors of my fish and the tank. Glows for a long time inside the tank. My niece loves it. On the first night, as soon as my Niece put them in, couple of them floated. Once we pushed them in, they went to the bottom of the tank and have stayed there since. My Niece now wants to buy the green gems for the garden. Also, I am very glad I bought the bigger size pebbles, as the smaller one might not have worked out for our cause. These are great!

I like seeing these in my fish tank. They are a really nice addition. It's really fun to see them glow in the dark. Although the glowing doesn't last a really long time I still say it was well worth the money.

These things are alright, but they're just so lightweight that when placed in water with any current they will float around. It doesn't look that great when rocks are floating.. These also don't glow very much.

I love that once the fish tank light is off, the stones still glo in the dark. And I also love the large size of the stones; and their very lite weight.

The glow is so dim, at night, that they can't be seen from 10 feet away. The would probably be pretty good in a flower vase of fish bowl.

Not so "glowy" They are pretty, but don't give off much light at night. I've had other items that were much better. Waste of money.

Let me first start off with the pro’s.... these rocks are nice and big with soft edges. They glowed in the dark the night I put them in my fish tank. My betta likes to lay on them lol. The only con is... they’re too lightweight and float up too easy. I had to put aquarium shells in with the stones to keep them down, as you can see from the picture. Which is the reason why I deducted a star. Otherwise, they look good in the tank, they glow nicely, and as I said have nice smooth, round edges. I’d love to buy another bag of glow in the dark stones, but preferably ones that are heavier that I can mix with these. As long as you weigh them down, they’re fine.

I'm so glad I ordered this size as opposed to the 'pebbles' everyone else sells! I put some in my fish tank and they glow all night. Now I've put the rest outside - friends have already asked me about them. I am really impressed with how long they glow!
