Exceeds Expectations
For context, I have a tank with American Comet Goldfish, and they’re utter vandals (or visigoths, maybe). I like to give them some features in the tank they can engage with. There’s a hollow log, which more than half of them could fit in at first. These days they’ve grown so big that fewer than half of them fit in it at all. They’ve taken to attacking the air stones, pulling the suction cups off the side of the tank.The jellyfish look good in the tank. They don’t “glow in the dark” but I have LED, not fluorescent lighting. They float in a very natural manner in the filter wash. The line (filament) attaching the jellyfish to the floor of the tank suction cups is very fine, almost invisible. I did need glasses to work with it. It’s strong, and the vandals have not detached the jellyfish in any way. The line also seems to pose no problem or obstruction for the fish.The jellyfish must have good “mouth feel”, since the fish have been chewing on them. They take a few inches of the tentacles into their mouths and nibble the bell or arms. They also pull on the arms and tentacles, and drag them around the tank and through the plants. I’ve had them for over a month and there’s been no damage or loss of pieces. Very sturdy. The alpha female (9″, 6oz) really has a go at them and they just bounce right back.

Cool jellyfish!
Why did you pick this product vs others?:These little jellyfish are so adorable in my aquarium and my fish absolutely loves them. This was the perfect touch to my aquarium and they look so pretty.

Looks cool
So I bought these jellyâs to add to my tetra tank. And they do glow and look cool but they donât stay suctioned and that gets on my nerves. After a few hours they become unsuctioned so you have to go back course the rock and re stick or they float to the top of the tank. Iâm probably gonna buy some small weights instead of suction cups they come with.

Pressure from filter causes bubbles
Beautiful decorations that light up the tank! However, the one flaw is that the jellyfish close to the filter are prone to forming bubbles that cause them to float sideways.

Excellent Toy for Aquarium Fish!
I bought these sweet jellyfish toys for my 45 gallon aquarium. I have 3 fancy goldfish (koi) and wanted to give them a toy to play with. I rinsed them well and put 2 of them in the tank. All three fish were very interested and played with them a lot. They nipped at the tentacles, plucked at the strings and tried to ‘bully’ them lol.I like them a lot, they look good in the tank and I have Fluval Lighting (controlled from my phone) and it has adjustable lighting for different colors. They look really good under the black light setting (so do my fish lol).Definitely a good buy for the cost.

String Does Not Securely Stay On Suction Cup and Breaks Easily Rendering Decoration Useless
I bought these to enjoy in my two 10 gallon GloFish tanks. The jellyfish themselves are beautiful and have cool colors and movement however, and this is important, for the prices of these jellys, I feel this company should figure out a FAR better way to secure the string to suction cup and send the product already assembled. The consumer must figure out how to tie the string to the suction cup, and the suction cups truly have no notches, or anything at all, to keep the string on the suction cup. Since the string is nylon, it tends to slide off the suction cup and is difficult to put it back on. When I managed to get it on again and tried to pull the string tighter, the string broke, rendering the jelly useless. I tried it with a second jelly, and without the string breaking, got it in my fish tank. In a short period of time, and despite tying four knots in it, the string dethatched from the suction cup entirely and my fish got caught in the string loop. I am pretty disappointed after initial excitement of finding these. A little imagination of this company could go a long way. They could have a loop on the suction cup itself, they could have small base like most decorations do with a suction cup at the bottom and have the base have holes in it so the string can be better secured. I am most likely going to return these items given their purpose is moot by design. Super bummer.

Same as the rest but always the best, price!
These are as good as any at a higher price as they are all made the same and you should replace them yearly anyway for brightness. Consistently the most talked about glow-light ornaments/plants from guests. They always ask if they’re real, I respond, “touch one, find out” LOL!

Cute.
These are very cute, bigger than I expected, but they don’t move!!? I’ve had several sets (bought at local retail stores) that actually moved around with the motion of the bubbles and water. I can’t tell you the number ppl that actually thought the ones I had before were real 𤨠lol. But EVERYONE that has seen these – KNOW its just decor.These just kinda set there. I have a 10 gallon tank – so I only put 2 in at first. Then took one out. So there is plenty in the pack for any size tank you have!The look of them aren’t worth having the clear string in my tank – with the chance of it causing harm to my fish.I’m not sure if they’re made from a different material or what? They just don’t move like others I’ve had. It’s a struggle to keep them open. I thought my Betta would enjoy swimming inside them – but he stays away from it…They are really bright and pretty with glo lights. There is just no movement at all.I will update with a photo when I get home.
