Fluval Flex 9 Gallon Glass Aquarium Kit, Black

Great starter fish tank. Sleek design. I decided to upgrade the filtration and return pump. I'm amazed by the build quality for the price. There are a ton of videos and aftermarket upgrades available for this tank. YouTube and Etsy are your friend for that. I'm looking to purchase the 32gallon version next.

For many years, I kept saltwater, brackish, and freshwater aquariums on a pretty large scale. I took a break from the hobby, and recently found myself ready to get back in the saddle, though on a smaller scale. I chose this aquarium for the Fluval name-- I had great prior experiences with Fluval filtration (loved my Fx4!!)This aquarium reignited my love for Fluval. Super quick and easy set-up, attractive, so quiet that you can't hear it running, and the lighting is really sophisticated-- fun to personalize the light settings!! I was pleasantly surprised by the technological advances (and reduced costs) offered by this aquarium, since I was last active in the hobby.Overall, I give this 5+ stars. I plan on buying this set-up again for my parents (and setting up another one for myself!). I do, though, have some suggestions to Fluval, as an experienced aquarist, as to improving this already great aquarium--1. The food slot in the front of the tank lid would benefit from having a sliding or hinged door. My cats sit on top of the tank and were easily able to get their paws in, until I installed a mesh cover.2. It would be nice to have the top hinged, so it would be supported whenever doing water changes.3. Even though this is a relatively small aquarium, I can see that there might be times that you might want to use additional equipment with it, such as a chiller, sump, or UV sterilizer. However, the current lid design, head space, and design of the partitions between the back chambers doesn't support this. It would be great if those areas could be re-designed to provide flexibility to use additional equipment, as needed.Overall, though, I adore this aquarium!! Already planning my next Fluval Fex 15 gallon tank. Stay tuned!

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!

The Fluval Flex Aquarium Kit has transformed my space into a stunning aquatic oasis. Its sleek and contemporary design, complete with LED lighting, adds a touch of elegance to any room. Setting it up was straightforward, and the filtration system is efficient, keeping the water crystal clear. The curved front glass provides an unobstructed view of my fish and plants, creating a visually captivating display. However, the provided filter media could be of better quality. Overall, it's a fantastic kit for both beginners and experienced aquarists, offering a stylish and functional home for my aquatic friends. It's brought tranquility and beauty to my living space.
