Beautiful Fish Tank?
I'm so glad I purchased this fish tank from chewy. It shipped quick and arrived in perfect condition, despite shipping damage to the box. So easy to set up, the tank and accessories are good quality. I'm very happy with the filter, it's a beast. I highly recommend this product!

Wonderful aquarium!
Bought this for 2 small goldfish. It's a great size and looks nice in my bedroom. The filters work really well. The only issue I've had is that it is so reflective on the sides. Probably need a background to prevent that. But this is an awesome aquarium. Highly recommend.

amazing fish tank!
So first I will say this is an amazing tank for the price! I got it while they were having the cyber Monday sale so it was alittle less than normal but even with that being said most fish tanks I found that came with setups for a 20 gallon were around $200 if not just alittle bit less than that. I haven’t put water in it yet because I am gathering everything I need first but if I can edit this I will let you know later. At first I didn’t think the tank was going to be in one piece when it arrived. The box was destroyed and it wasnt sealed, the top was open. When I opened it everything was still completely in tact and looked great. It is...

Wonderful tank
I've had this thing for 4 years now and only just need to get a new top because the lights are going out and don't look replaceable.

Fish tank
The fish tank was a gift and she loves it. She said it was easy to set up and everything works great.

Great Starter Setup!
Tank is great, filter works well and is very quiet (I added a second filter but it really wasn’t needed, I just like to have extra bio filtering), heater does the job, hood is lightweight but looks good and light is very bright (I did replace with a glass top and different light, better suited for growing live plants, though). If you’re just starting out, or getting back into aquarium keeping (as I am), it’s definitely worth the price.

The Perfect Nano Tank
This tank has been perfect for my Betta. He seems to love zooming around and checking out all of the hiding places I've made for him.

Perfect Betta Aquarium
I love this aquarium for my Betta. It is just right for him and a few shrimp and snail inhabitants. It arrived in perfect condition and I would highly recommend this to anyone!
-
Good quality nano aquarium
The quality is fantastic and it's not even that heavy! 10/10. This tank is good for keeping some guppies, Betta and more nano fishes.

this is a very nice tank
I really love the quality of this rimless tank. The back filter section is big and the glass is put together nicely. It has a filter sock and a return pump, unfortunately the pump is surprisingly loud and annoying so I will have to replace that but it’s such a nice looking tank I couldn’t dock a star for that. Tank stand I got on another website but it fits almost perfect. Super happy!!
Best Betta Fish Tank

Very good quality.
I bought two and love them! Though I would never recommend them for fish (even without the dividers- too small), I love it for my plan of divided colors of shrimp and ramshorn snails.
-
Nice quality!
This is such a nice little tank. I personally wouldn’t recommend it for a single betta nevermind 3! Maybe some sort of insect pet instead. I’m using it as a terrarium.

Very nice little tank
This is a very pretty glass tank with black silicone accents. It was well protected when shipped and arrived with no damage. A tank this size works best with juvenile or small female bettas, but with dividers removed is plenty big enough for a good sized male. I am currently using it as a hospital tank for a guppy. It will just accommodate a Small World filter and one of the rectangular 10 watt heaters. My only issue with it is that the glass top fully covers the entire tank. It seems to me that in an unfiltered tank it might not provide enough oxygen exchange for air-breathing fish. There are no cutouts/spaces for the heater and filter...

What an upgrade!
I recently, finally “crashed my tank” as they say. So badly, the whole thing had to go. Im not sure what algae bloom we caught but I spent WAY to much time cleaning a tank that would turn brown every 4th day. Plus, its saltwater!! Exhausting. So I bought this tank and we anxiously awaited its arrival. My only wish was that the tank came with an optional, matching heater.

5 Gl Aquarium
Easy to clean and I like the filter setup. Plastic is lighter to carry to the sink for clean out. It all works well.
-
ease of water change
doing weekly water changes is a snap with the smart clean filter! The 'bow' gives the tank a larger appearance which is nice for viewing my fish. Great Job Aqueon!

Great easy water changer
So happy with this aquarium. Runs great I love that u just lift slide the nozzle and the water comes out. No tubes nothing. For weekly water changes it’s so convenient!
