I think you could use them in an aquarium. Never thought of using them for that, myself, but a good idea. I would expect since they are a type of 'rock' they should sink, which would be perfect. Think I will put a couple in my own aquarium!

I have no idea. I would think they would sink, but then how would it effect the glow?

Yes. We have 300 scattered with other rocks in a rock garden. They truly glow in the dark (even better when there isn't a full moon). I just took six pebbles and put them in a bowl of water. They did not float. Should be perfect in an aquarium in a dark room!

Yes sure. In fact, I think they would last longer if not floating in a pool. I keep mine in the pool all the time now though.

In my experience, they did NOT float but that could be because I placed enough (lots!) in my wedding vases to hold up the flowers in the center pieces. I also used waterproof LED lights in these vases.

They float. They will eventually sink, but my daughter drops the magnet down into the water & is able to catch them that way. We've not had any issues with them not coming up out of the water. The toy can also be played with out of water.

These beads Don't float. They are gel like marbles . There is some other gel for these to float in I looked into it and what you want is "wholesale transparent water gels" on amazon

They will definitely float. Same kind of styrofoam that you would find in a bean bag

No, I would not just drop these in your tank. They are used inside the filter so beneficial bacteria will grow on them. If put correctly inside the filter, your tank will be much better off and will cycle much quicker, easier, and maintain good water conditions.

They were a gift for my niece, so I really do not know if they float. I believe they do... but am not 100% sure.

Yes they do sink! They're solid plastic and somewhat small. I'm not sure how big you're looking for but they're cute table toppers which is what I purchased them for

Yes they sink. But be warned that they aren't very bright so you might not see them well under the water.

hello sophia,first, have you put a few drops of dishwasher detergent in the tank and used distilled water? second, it depends upon WHERE they are getting stuck. sometimes, mine would get stuck in the corners underneath the motors, so i put a plant or decoration there so they can hide there. also, if they get stuck in the center of the aquarium, you could put a long decoration there like a sunken ship. then they will fall onto and rest there. since it's higher up than the aquarium floor, they usually get sucked into the water flow easier. good luck, dan

Yes, but due to all of the channels for bubbles of air to be trapped, they will float. You can force the bubbles out by shaking them under water, but they stop floating eventually anyway.

I don't see why not if you are buying the smaller pellets and the fish are already big mouthed. For instance, these don't work well with guppies whose mouths are too small. The fish need to be able to grab the pellets. The pellets don't muddy the water so a tank should be fine. Is there room in your tank for the fish to jump at the pellets without hitting the top of the tank? The pellets will float on the water. They are designed for fish that have colors like Koi and large goldfish. Have you considered purchasing the flakes?

The water pearls themselves do NOT float. However, if you put enough of the water pearls in a container of water anything placed on top of them would give the appearance of floating in the water. Kind of like setting something down on an invisible shelf.

I don't know if they would even work in the water or not but they will work on the outside. I'm just not sure how they will look if you want to put them on the back side of your aquarium. They will be backwards and probably not as vibrant but they are great stickers!!

No it does not float... However, I have used an inner tube under them to cover the entire pool with them. One of the pictures shows this.
