- New to Fish Keeping? We've Got You Covered. Tired of worrying whether your fish is fed, the water stays clean, or the temperature is right, especially when you're traveling for work or on vacation? The Jengu M1 is a complete smart aquarium. Actual water is about 4.5 gallons, so it is ideal for a betta, a few guppies, shrimp, or snails. It handles daily feeding, monitors water temperature, and is fully controllable from your phone. No extra parts to buy, no guesswork. Set it up once and enjoy your fish. Perfect for beginners and busy people.
- Easy Control, Your Way. Too tired to get up from the couch? Use the free Jengu app to adjust lighting, pump flow, feeding schedules, and child lock right from your phone (requires 2.4GHz WiFi, 5GHz incompatible). No WiFi or phone handy? The four physical buttons on the lid work completely offline same controls, no network needed. Technology makes it easy, and you still get the satisfaction of doing it yourself.
- Never Miss a Feeding, Even When You're Away. Gone for weeks at a time? The built-in automatic feeder schedules meals and sets how many portions per feeding from your phone, so your fish eats on time even when you're not there. Tap the lid button for an instant snack when you're home. Important: the minimum portion is made for small community fish. If you keep a single betta, feed every other day, not daily bettas eat everything you give them and can bloat or die from overfeeding. Use pellets 2mm or smaller in diameter so the feeder dispenses reliably every time.
- Quiet Enough for Your Bedroom, Powerful Enough for Clean Water. The 3-speed pump runs at just 28dB, quieter than a library put it on your nightstand and it won't disturb your sleep. Pick the flow that fits your fish: Low (2L/min/32GPH) for betta and shrimp, Medium (3L/min/48GPH) for guppy and tetra, High (4L/min/63GPH) for goldfish or extra filtration. Run it low at night, high during the day. You'll forget it's running.
- Clear Water and Healthy Fish, Without the Hassle. Two-stage filtration keeps the water crystal clear: the mechanical cartridge catches debris (replace every 3 months), and the biological media grows beneficial bacteria that keep the tank stable (replace every 6 months, never rinse it with tap water). The built-in sensor also tracks water temperature and sends phone alerts if something is off clean the probe monthly for best accuracy. Less time cleaning, more time enjoying your fish.

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 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.

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.

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.
