  • Great Tank
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

  • It’s more than a gallon smaller than listed
It’s a 2.64 gallon tank and not a 3.7 gallon tank. Not returnable.

  • Good little tank
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

  • Really cool complete aquarium for small fish or betta.
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

  • False Advertising!
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

  • Filter not working properly
Love the aquarium appearance, size and shape, but after one month the filter is making high piercing noises. I’ve tried several things to correct it. I’m now looking for a replacement filter. It’s not a pleasant noise and every so often completely stops. I’m glad I have another tank to transfer my fish to until I find a new filter for this one. ... show more
