The fish tank I never knew I wanted
I absolutely love this tank—it’s modern, beautiful, and has completely exceeded my expectations. I paired it with a BioOrb décor set, which I also love, and everything feels high-quality and well-made. The packaging was great, and after 3 months it’s holding up perfectly. There’s a little algae growth, but that’s probably because I keep the light on so often—I can’t stop admiring the tank and watching my fishies! My 3-year-old talked me into getting the fish, and now it’s turned into a whole family favorite. This is honestly the dream tank I never knew I wanted. Highly recommend!

There is a small hole in cover that can fit a cord for heater
Pros: very quiet, ultra clear, practical dimensions, easy to set up, bright light, sleek design, would look good with a variety of interior design styles. Cons: light isn’t dimmable (worried it’s too bright for my betta), limited access via cover in the top, pump only has one speed, view distorted at curved corners. This is a great small aquarium, my betta seems to be very happy since moving in. It wasn’t apparent from the description and photos that I would be able to run the heater cord through the lid, but there is a small hole just behind the power cord connecting the light that fits the heater cord perfectly. The minimal design is unobtrusive and the filter pump is very quiet.

looks cool but is bad
-very loud air pump no matter what I do. -light is very bright and not really suited for plants -internal filter carts they want you to buy are a scam and expensive. filter Medium is too small, and doesn't really need to be replaced like they suggest. Same with the sponge, you can rinse your sponges/medium in aquarium water and get a lot of life our them. Just a huge waste of plastic if you follow their suggestion of buy new filters everytime and is also counter productive to keeping a cycle since new bacteria needs to be established. - internal filter idea is interesting but will consume and kill nano fish due to how the intake works. killed quite a few of my fish. - cleaning is a pain due to small lid - adding heaters or anything else looks bad since there is no extra holes. have to keep lid off or slightly off for space. - air intake tube for filter is at bottom of tank, when it inevitably fails it will leak everywhere. I finally managed to get it in a functionally better place after heavily modifying it but you loose the minimal look in the process. my mods are - - removing the internal filter entirely, its easy to do just remove some screws. using small plastic sheets and aquarium silicon I sealed up the hole. - made a custom laser cut lid that has mounts for a better light and holes for whatever (air tubes, heater cords etc) - added a basic filter, in my case a small sponge filter but anything would work. worked great once tank was cycled.

Decent but some big pros and cons
Big pros: everything comes together, optional decor that covers the filter nicely, no need to search for different aquarium parts to cobble together, you know how much you’re going to spend because it’s a kit. Also, the filter is easy to remove and clean if you’re using the right size of rocks and stratum Big cons: the filter would be terrible for fluval stratum so no aquarium plants with deep roots or shrimp hiding places if you have an aggressive fish like a betta; the light and shape distortion on the corner of each face is annoying. Overall, this is a good kit for the size and what you get. I hadn’t put together a tank in 20 years so I wanted something easy. This is a nice decoration piece in my living room but I wouldn’t buy this again because of the corner distortion. I would have gone a little larger with a 14 to 20 gallon tank so I could have a larger number and more diverse type of tank creatures and a different filter setup for fluval stratum. I have had ZERO algae issues. Keep at least a couple different kinds of plants, keep a couple of nerite snails, and keep up with sampling your water (the API chemicals and kits are good) and cycling your water otherwise the tank type won’t matter.

j'ai achete cet aquarium car je le trouvais tres beau seulement apres plusieurs tentatives avec plusieurs poissons de differents types, ca n'a jamais fonctionne... et c'est la que j'ai compris pourquoi il n'y avait jamais de poisson dedans dans les modeles d'exposition que l'on peut voir dans les magasins !!! La pompe de filtration est beaucoup trop forte et perturbe beaucoup trop les poissons. Les parroies font un effet miroir et ce n'est absolument pas adapte pour un combattant. Bref... passez votre chemin si vous voulez vraiment avoir un aquarium avec des poissons dedans.

Absolutely beautiful tank, looks great and smart, my last biorb lasted 12years as to why I have brought another one but down sized to a smaller tank this time 🥰 They are easy to keep clean when changing the filter every 7 weeks. Well worth the money and love the LED colour change function. Pump is really quiet compared to my old biorb 🤭 and my fish look really happy in there new environment. I would say that 7 fish is enough as to many can make the tank more dirty and stress the fish out as only a 15l The bubble function is awesome, I did also get a smaller heater off amazon as it’s a smaller tank. What came in the box was a filter, air stone and gravel. I didn’t use the gravel that came in the box as I used the ball stones from my old biorb tank.
