Features
- FITS RIGHT ON YOUR DESK - Smaller than a sheet of paper, one cord only. This 2.1-gallon tank measures 7.5"L x 7.1"W x 9.1"H and slides onto a desk, nightstand, bookshelf, or dorm shelf without crowding anything. One cord powers the whole tank no tangled wires, no fighting for outlets. Great for a single betta, a small guppy school, or shrimp. Keep it in a cool spot away from direct sun.
- 5MM ULTRA-CLEAR GLASS - See your betta's true colors, crystal clear. High light transmission shows colors vivid and true-to-life, without the dull cast of standard glass. The one-piece front panel has no center seam for a clean look. A clear view from every angle.
- ALL-OVER COLOR - One fresh color, every single part. Back chamber, base, lid, LED housing all orange, all matching, no random clear bits breaking the look. It is built to be noticed: a fun, bold piece for a desk, shelf, or kid's room, not another see-through glass box. The lid keeps jumping fish in.
- DUAL-STAGE FILTRATION - Mechanical and bio filtration for clear, stable water. Mechanical wool traps debris while three layers of bio-foam provide surface area for biological filtration. The modular cartridge pulls out and slides back in no cutting, no trimming, no taking the pump apart. Swapping media takes seconds. The whole chamber lifts out for deep cleaning with no hard-to-reach spots.
- 28dB QUIET PUMP - You hear soft water, not a mechanical hum. The 5W low-voltage USB pump runs at around 28 dB quieter than a library. No buzzing, no rattling, just calm water sound. USB power means it works with a wall adapter or a power bank for backup.
- COMPLETE STARTER KIT - Open the box, fill with water, plug in. In the box: pump, LED light, mechanical filtration, bio filtration, lid, and instructions. About 10 minutes from box to running tank with one-button operation, no confusing dials. Arrives ready to wrap for birthdays, Christmas, or a just-because gift. Heater, fish, decor, and food sold separately; the back chamber fits a small heater.
- LOW-MAINTENANCE SETUP - Feed and top off water that is daily care. Built for beginners, students, and busy schedules. The filtration keeps water stable, so you are not doing constant water changes. Day to day: feed your fish and top off evaporated water. Check the cartridge once a month; rinse or swap when dirty. Kids can help feed and observe, learning responsibility without parents managing every step.
- A GIFT THAT BRINGS LIFE TO ANY ROOM - This complete, ready-to-use kit is ideal for betta enthusiasts, first-time hobbyists, and kids curious about aquatic life. It also makes a thoughtful housewarming gift a living piece of decor that adds calm to any space. Arrives ready to set up, so the recipient can start the same day.

LOVE this tank. We use this for our male double fin betta, and a few shrimp, the tanks display is so helpful with making sure our temp is consistently good (make sure you buy a heater as it doesn’t come with the tank. It took a second to understand how to work it, but it’s INCREDIBLY easy once you understand the basics. The size is perfect to be in my single wide, but still makes a big statement. Glass is durable, and so is the lid/all parts. On the display you can change the light settings, feed your fish, and turn it on or off. There’s also a child proof setting where you can run the tank from your phone, so if a cat or kiddo tries to change the settings on accident- it won’t work. The app has been reliable, and we’ve had zero problems with it communicating with the tank. I was hesitant with how little reviews it had.. but truly the best tank we’ve got, for a very reasonable price. The glass is clearer than any tank we’ve purchased at petco. Looks very nice.. has a ton of different light settings so you can grow plants, have a nice ambience, etc. The app also lets you add a feeding schedule and a lighting scheduled so you don’t over do it. Or if you’re gone out of town for a few days, your tank still functions as if you were there turning the light on. The only thing I would change is the amount of food it automatically dispenses. It’s too much for our single betta, so we’ve had some problems with “over feeding” … but still VERY cool if you can’t physically feed. We have two curious cats who can’t hurt our little betta buddy.. overall I would purchase this tank again!

I’ve really been enjoying this aquarium. I’ve had it for a few weeks now and appreciate that it has an app wherein I can control the lighting (set timers) feeding, and adjust the pump setting. I found it easy to set up and very attractive. I chose the black aquarium because I wanted the black background to better show off my shrimp & plants. There are a lot of different lighting features to choose from -and even lighting that specifically promotes plant growth. My little shrimp seems to love it and shrimplet babies have hatched. It’s quiet and for the size of an aquarium you really don’t need a heater or anything- so basically it comes with everything except for whatever substrate or decorations you want to add. Highly recommend for shrimp, a betta, or small schooling, fish like neons or guppies.

Loved this smart fish tank at first sight, and really like the filtration system and the legs underneath. It looks nice on my nightstand where I can see my fish while lying down. However, for the price I expected it to not become faulty and so quickly. The built in light will not turn off and it gets really hot!! It suddenly went up to 86° and I am upset and worried about my fish. This is unacceptable and I want to be compensated. Amazon is replacing it...with the same one...and said it would be shipped overnight. Nope. It won't arrive for four days!!! I opened the lid hoping it will cool the water, but it has only gone down to 82°. Who is going to replace my fish????

I had tried several fish tanks until finding this one and I am really happy. It’s easy to set up, and although you have to buy the heater separately,‘it’s worth doing so. Since it can be controlled via the smartphone app, one can control the light, feeding and water pump pressure. I suggest to establish the routine early and just monitor from time to time to ensure the functionality is working with your fish and its life. Mine took happily to their new home. Also, it’s incredibly quiet. Make sure to at least take the filters, including the water pump out and rinse it out once a week for better circulation and cleaner fish tank life. The parts can all be found in Amazon. Get one extra set to have it handy. I’m really happy with this investment for my fish and their general health life. I also suggest silicone ornaments vs plastic, to avoid hurting the fish with sharp edges. A couple of snails wouldn’t not hurt.

I only have this little tank starting to cycle, so i can’t give an opinion on life span or the filter performance. The tank is a really nice size for a desk. I have mine on my cutting table. I have a small Etsy store and make bag, wallets, quilts…so I spend a lot of time at my cutting table and wanted a buddy. It is a very compact tank, is incredibly easy to assemble and runs very quietly. Right now I have a bonsai lotus in a small aquarium pot. I really like the simplicity and clean lines of this tank. It would fit into a minimalistic house decor style, my studio is not minimalistic, but it fits the space I had that I could sacrifice. Currently I have a few pest snails in it to help the cycling. I prefer to do a fishless cycle, but you need something that will create waste to help the cycling process. I was going to use black sand as the substrate, because plants grow better in it. The filter area has and intake near the bottom on the tank, so I decided to use polished black stones and raw amethyst crystals as an accent. I haven’t had three tank running and I haven’t been home enough, to really create the look I want, but I will try to remember to add some pics to my review once it’s done. The light is more of a spot light, which is really a neat concept, but bonsai lotus plants need a lot of light for good growth and a lot of food, so i ordered a small clip style grow light to supplement the light for my plant of preference. I don’t think the substrate will contain enough food for the lotus either, so i will just use root tabs, as I do in my larger aquariums. The material used in every part of the tank is sturdy and well planned. For the all in one, compact design and basically “plug-n-play” so i think. It is a good value and I really love the filter not being visible and the cords being USB-C size. Onto the functionality of this being a Betta tank…I know they are sold in cups and are usually badly neglected, so just about anything is better than where they are. I’ve always used the rule of thumb, that 1” of fish needs 1 gallon of water. Betta, particularly grow larger than 2” as adults. The female Betta tend to be a bit smaller, so I’d probably only use this for 1 female betta. I think some of the nano fish would look great in here and you could do a small school of those, but that’s just my thoughts on the size. I haven’t decided what I’m going to put in here yet, but I will stick to my rule of thumb. I do have a few larger tanks, and have looked at larger versions of this type of tank and I’m really considering switching the other tanks over to these.

Automatic fish feeder puts tons of food out, so you need a decent amount of fish in your tank to eat all the food

Got it for mu husband's birthday. It works as expected and has a companion app that lets you set a schedule change the light colors and feed the fish. The filter seems to work well. I haven't tried to get replacement filters yet and hope they are easy to get as this doesn't seem to be a mainstream company and is based in China. It looks nice and the sound level is that of a snall water fountain and it is pleasant. Quality seems to be there as well. Took me a while to figure out how to balance the lid while cleaning. It's not on a hunge but has a place to holster it as it's connected to the tank with cords.
