    • Beautiful!
Color: White Size: 9 Gal.
The media could not be loaded. This is such a gorgeous fish tank. Well made and thought out. One gripe is I want the lid to tilt back so I don’t have to place it somewhere or hold it, but that’s really minor. My betta doesn’t have an issue with the current, but he’s a strong swimmer and short tailed. The filter is very nice, but I found the lighting confusing. The remote is weird. All in all, great tank and I’d buy it again. ... show more

    • We love this tank!

After dealing with multiple issues with BiOrb on Amazon, our School at a University decided to go a different route and try the Fluval Flex. It was not a disappointment at all. This is a very spacious and gorgeous tank that was easy to assemble and gorgeous to look at. Admittedly, I did have trouble with the remote to the fish tank light, but that's on me and not the tank (the sensor is at the top so you have to point at it which I wasn't doing). It's really fun to be able to change the colors and dim or brighten them. Very quiet and so far our fish are enjoying the added space. Incoming guests as well as the college students love coming in and watching the fish. Thank you Fluval for being wonderful (and for not being BiOrb)! ... show more

Looks very nice. Perfect size for a betta. The pump is quiet. The remote controlled lights are a nice touch.

    • Nice quality tank!

I really like this tank! I was looking for a nice small tank for a planted aquarium. The bow on the front really makes the tank unique and adds a sharp expensive look to the tank. The quality of the glass is nice and the black beading on the back wall and the top rim of the tank really helps clean things up. It nicely hides all the equipment and pumps in the bank and give a nice look to the waterline. The light fixture came DOA, but the seller quickly replaced it and it is now working great. The light is bright and provides a lot of custom options. It may not be the strongest light for a planted tank, but sure looks like it will be more than enough for the plants I am growing. The real compartments are large enough for your own mix of equipment and filter media. The grates on the intakes are a nice touch and will keep small fry or shrimp out of the rear compartments. I added some small filter material inside these grates to further decrease the chance of fry or shrimp entering. The pump is quite strong and is completely silent. I cannot hear it run at all. The tank sits next to my bed and you wouldn't think it was even running. The tank also came with a nice mat for the bottom glass. Overall I am extremely happy with the tank. Ignore the bad or misleading reviews. Perfect planted tank. Great quality and a great price point. Thanks! ... show more

    • Spacious and Effective
Color: White Size: 9 Gal.
Review Image by Julia Julia
I love how the filter and heater (I purchased separately) can be hidden in the back. An aesthetically pleasing tank was important to me as well as obviously giving my fish a good quality of life. My betta loves to lean against the intake filter and just chill there. However, I think the flow of the filter is a bit too high for betta fish. I put 2 extra sponges in the back to try and buffer the flow, but it doesn’t seem to do anything. Another thing thats slightly annoying is that the lid has no stand for when you are opening it. Water drips everywhere and makes water changes more annoying than they already are 😅. Overall this is a great tank if you hate seeing all the ugly wires- but you might need to make modifications for certain fish because of the filter. ... show more

I bought a used tank for cheaper, which I was weary about because what if it was cracked or damaged or had a leak? I rinsed it out and put water in it and so far so good (it's on the cycling process right now), but then I realized that the pump wasn't working for me! I put it in different outlets to try and see and it still wouldn't work. I messaged the company and two days later, they responded, but they sent me a new pump for free! So they were a very nice brand to get ahold of and didn't even question it when I asked what I could do. The lighting works great. Their pump water flow was pretty strong so I did what another reviewer said and I bought those foam things to put on top of them, also from the brand fluval, which really slowed it down. I also bought the 15 gallon heater that fluval offers, which I bought used too, and it works great. Some reviewers mentioned the hole at the top, but if you have floating plants that can cover that space, I'm sure it wouldn't be an issue. Or get a piece of mesh if it's bothering you. It's really not that big and if your betta jumps through that, you might want to invest in teaching it to do some tricks because that would be impressive (I can only say that for the 15 gallon, I don't know about the 9 gallon). Anyway, I love my new tank! ... show more
