This was a top quality tank to start my shrimp keeping journey. Easy to set up, the divider at the back keeps everything hidden and very tidy, and it's a breeze to set up. The pump is very quiet, and a regular filter clean keeps everything as it should be. My shrimps are breeding which shows they are in a great environment.

Ive had my tank almost a year now and its been great! The internal built in filter is low maintenance (rinse the medium now and then). It keeps my tank nice and clean looking and is very quiet. Ive never had any water parameter difficulties. I use black sand as a substrate and the filter has never picked up particles. Its very well made and looks/feels luxurious.I do need to take a star off because the built in lights started malfunctioning after about 6 months. It constantly flashes dark blue lights at random when lights are switched off. Ive tried every setting and unplugging, but nothing stops the lights except turning the lights on intentionally. It doesnt impact functionality at all and I have gotten use to it, but I do worry about the longevity of the LEDs with blue lights always flashing for no reason.

I already had the 9 gallon. So when I wanted an upgrade this was a no brainer. I love the fluval flex. Keep water clean, clear and the fish look happy. Tons of lighting options and it looks good too. Seller sent fast and is exactly what I needed. Thanks

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)!

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.

Not in the description on Amazon or anywhere else is there any mentioning that this aquarium must be connected to 110V. Not even in the product description.The only thing that made me suspicious was the plug, which is rather unusual here, and I only found the necessary information on the plug itself.Unfortunately, a return is not possible for various reasons and so I am forced either to make something myself or to buy expensive spare parts.

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!

I've always heard great things about Fluval and when I saw this tank, I really wanted it. Aesthetically, the tank is beautiful. The lighting is great, However I ran into a few issues with it.1. The biggest issue I have with it is my particular tank is running hot. Running on the base equipment, i.e. the lights and filter and nothing else... My tank has reached 84 degrees and was still climbing before I manually cooled it down by floating multiple bags of ice in it. I have a fan sitting on top of it right now, blowing into the tank to cool it down, with the hood cracked open to let the heat out, and my ceiling fan is on full blast, with my AC down to 76-77, and it sits at 79 (which is a temperature that I wouldn't mind, if I wasn't taking all of these extra measures to keep it cool). There's no heater in it, and I have an air pump in there - Which I've disconnected and watched to see if that was the issue.-I've contacted the manufacturer about it and they're blaming it on something on my end, claiming that my thermostat is probably wrong and it's probably hotter in the room that the tank is in (even though I have thermometers that say otherwise), and they keep ignoring my questions about the LED possibly malfunctioning or what not... as if the LED wiring can't possibly have a wire messed up (Like my local fish store actually suggested when I explained it all to them, which makes sense when you feel the hood where the light bar is... It's rather hot...)2. The thing that I could deal with but the above situation has just really put a bad taste in my mouth for this tank -The overhead water flow from the filter is very strong. My fish go up to the water surface over by where the feeding space is and get tossed against the glass from the water coming in so harshly. The filter is non-adjustable so there's no fixing it from that end.3. The slots for the water intake are HUGE. Any small fish that you would keep in this aquarium can fit right through. I've added a filter sponge cut out for that section to block it all off to take care of that.All in all, the tank is beautiful. The lighting is great and grows plants pretty well. However the overheating is very frustrating and the customer service leaves a lot to be desired, as the latest thing is "Well what type of fish are you keeping anyway" - like that should really matter. My 5 Guppies might not mind it, but the Rasboras that I have ordered might be a little toasty in a tank that's above 80.EDIT: I'll just flat out say it, After all of the email correspondences that I've had with Hagen "Service" representatives, they are absolutely the WORST customer service representatives that I have ever had the displeasure of conversing with. Lord help whoever has an issue with their tank, because they surely won't assist you in any ways. I'll be making a HUGE note of this for future purchases.
