Koller Products 2-Gallon Hex Aquarium Starter Tank - LED Lighting (7 Color Selections), Impact-Resistant Plastic Fish Bowl for Betta/Nano/Goldfish, Wedding Event & Home Decor

Love the different color lights. My grandson uses it as a night light. It’s nice. The light goes out after so many hours we bought this for his beta fish plenty of room.

I loved the concept of this tank and I wish it was actually as good as it looks. ;( But this is a weirdly designed tank, and NOT true to the pictures posted by the seller. - It is not made of acrylic, as expected (although the item description doesn't actually state what material it's made out of) - it is made of plastic, like a clear milk jug. It's flexible and the sides can be squeezed, even when it's full of water. - The bottom is not flat, for some completely bizarre reason. The ad pictures show the tank sitting flat on a table, but that is completely false advertising. The bottom of the tank has a bump out that cause the tank to not sit flat on any surface - see attached pics. The "bottom" of the tank actually hovers about half an inch above the surface the "bump" is sitting on. - Because the tank is made of flexible plastic and the bottom isn't flat, if the gravel and decorations inside the tank aren't perfectly balanced (weight-wise) on all sides, the tank will not be level - this is obvious if the tank isn't full to the very top, you can see the water filling one side before the other. - Because the tank doesn't sit flat on the surface below it, the entire tank rocks when you push the button on the top to toggle the lights. (You can solve this by picking up the black piece, which is the light housing and is not attached to the clear tank lid, turning the lights on, then replacing it on top, but you shouldn't have to. The tank should have been designed for this to not be an issue in the first place.) - Due to the material, I wouldn't trust a heater in this tank, even the small under gravel heaters they make for betta tanks. - There is no way to disable the "auto-off after 2 hours" feature of the lights, which the instructions say is factory preset. Fortunately, that feature doesn't seem to work anyway, I've had it on for 2.5 hours so far, and it's still lit. - Although there are no seams around the sides, the "corners" where the plastic bends distort the view inside the tank, creating split and mirror images. All that being said, the tank *looks* pretty nice, other than the (extremely) annoying fact that it doesn't sit flat on the countertop. The fact that it can run on batteries and is literally cordless (if you don't use a heater) is very convenient. But for the price, I expected better quality, and that bump on the bottom is not only completely nonsensical, as explained above it creates several other logistical problems with the tank itself. Overall I can't recommend.

I wanted something that was easy for my boys to experience a mini fish tank without all the responsibilities. This is the perfect size for their Betta fish, they don’t require much!

The lighting went out after the first week. And no, the batteries aren't dead. At least it does its job. Its not glass. Its made of a thick plastic.

Really nice shape (I bought the 2 gallon). My Beta has plenty of room to swim around. The light doesn’t work unless you keep it plugged in. I gave it 3 stars because it is not stable. The design does not sit flat so it is wobbly. If you bump it , it will spill pretty easily. That is my biggest complaint. I have to watch it around my cats. I am thinking I may send it back and get a round one. Too bad because I love the octagon shape… just really unstable.

Lightweight but sturdy! Perfect for a beta and a few snails.

It's beautiful and I would have liked to give it a 5-star rating but would have preferred an acrylic container. It's kind of a hard plastic and was dented on one side when I received it, but fortunately I was able with a push to get it back in place. A glass container would have been too heavy especially for lifting and cleaning purposes. I have yet to try the lighting as the cord for the lighting is very short and I need to have an extension cord on the display table in order to facilitate the lighting.

I used this for the one goldfish that I had for close to 4 years now. It's bigger than his last tank which is good since he grew quite a bit. There's nothing I dislike about it, I just won't be using the light, he's not a fan of them. lol

Great tank

It's like ur looking through the wrong prescription glasses. The angles are awful and it's hard to see fish because the plastic it's made out of is so flimsy and cheap. Very disappointed. I think seller should refund Immedietly instead of making it such a pain to return it.
