    • Great little tank.
Color: Black
Fantastic little tank. Smart style, great lighting system. Perfect as a starter tank, quarantine tank, or nursery for newborn fish. I just love t.

    • Not a good design
Color: Black
The design needs to be redone. The lid cannot be taken off...ever. The filter is attached so you have to take the filter with the lid. But the filter is the enter system of the tank, so you would have to turn it off. But to turn it off you have to turn the lights off too. Its a mess.

    • Good little tank
Color: Black
Review Image by Katherine S
Update- 4 months in and the pump stopped working. So far so good! I’ve had the tank for about 2 months and it’s worked great so far. This is my first time having a fish tank so it’s been easy to use as a beginner. Some reviews said that you can’t adjust the brightness of the lights but I figured out that you actually can through the app. You have to download the Petkit app to adjust the brightness (which isn’t in the instructions I watched someone else’s review video and found that out). It’s a nice size for the few goldfish I have. Cleaning the filter is easy and it’s kept the water clear. ... show more

    • Very happy
It works as expected, looks great, and my fish is happy. I really appreciate that the pump and lights use one cord, a large space for bio media, and plenty of extra space for other filter media. I use generic filter sponges cut to size instead of the proprietary filters it comes with. Setup was easy and the pump is virtually silent (with air valve closed). The light color and brightness can be adjusted with the app and has a timer for on/off. One issue is the app has a bug that prevents the device location from being set preventing the automatic light control feature from being used. Other than that, this is a great tank! ... show more

    • Really cool complete aquarium for small fish or betta.
Color: Black
Very nice all in one aquarium with a simple aquaculture setup. I really like this and it’s also a cool learning setup for kids working with basic aquaculture principles. It’s great that it includes everything needed besides live fish and plants of your choice. Set up and instructions are straightforward and betta or small fish are relatively easy starters. It’s a great looking mini aquarium and has potential to become super cool over time as plants become mature. Another benefit is constant watering although evaporation water needs to be monitored, so if fish feeding can be managed, then watering over a vacation is easy. Really nice addition to a room or office. ... show more

    • Great Tank
Color: Black
Review Image by Da 3thunleashed
The media could not be loaded. Great size for Beta fish, come in great packaging. Easy instructions for install, and yes super quite. In the video, all you hear is an air filter not the water pump. It came with a small gift which is a spare part. Much appreciated it !!! But its a good buy worth the price. ... show more

    • False Advertising!
Color: Black
The tank is inches smaller in ALL dimensions than the specs in the description and not even big enough for our betta. The length is 2.5 inches shorter, width and height are more than 3 inches shorter than the description. When I checked the measurement info, all it gives is the tank volume and that's obviously less than listed, too. It will be donated to a local charity and written off on our taxes so I don't have to box it all up again to ship back. ... show more

    • Color me impressed!
Review Image by Jennifer
The media could not be loaded. Absolutely love the lighting feature that changes the substrate and decor of the aquarium giving it a whole different vibe/look. Great starter size for someone with a betta. Realistically this is more about 3.5-4gal which is still great for a starter size. Wish this would come in a realistic 5.5gal or 10gal tank. Either way, absolutely love this tank! ... show more
