Jengu Smart Fish Tank Kit, M1 18.9 L App-Controlled Aquarium with Automatic Feeder

Jengu M1 is a 5-gallon (18.9 L) app-controlled smart aquarium kit designed to simplify everyday fish care, with a built-in automatic feeder and 5 mm low-iron glass.

• Free app control plus four offline lid buttons — adjust key aquarium settings with or without a network.
• Scheduled automatic feeding — set meal times and portions from your phone while away.
• Three pump speeds at 28 dB — choose a flow rate to suit different fish and room routines.
• Two-stage filtration — mechanical and biological media handle debris and support beneficial bacteria.
• Full-spectrum LED with seven modes — light the aquarium and support live plants.
• Tank, smart lid, feeder, light, pump, filter media and setup materials included — the core aquarium equipment comes in one kit.

Jengu M1 is made for new fish keepers and busy owners who want routine feeding, water-temperature monitoring and adjustable aquarium settings in one setup. Its open swim space is 900.6 in³ (14,756 cm³), with room for a betta, a few guppies, shrimp or snails. The kit is also suited to a bedroom, a home with children curious about aquatic life, or a room where a compact aquarium can be part of the decor.

How can I control the Jengu M1 aquarium?

Use the free Jengu app over 2.4 GHz Wi-Fi, or operate the four physical buttons on the lid without Wi-Fi or a phone. The app adjusts lighting, pump flow, feeding schedules and child lock; 5 GHz Wi-Fi is not compatible. A temperature display and built-in sensor monitor water temperature, and the sensor can send phone alerts when readings are off.

• Set light brightness and timer from the app.
• Clean the temperature probe monthly for best accuracy.

How does the automatic fish feeder work?

The built-in feeder lets you schedule feeding times and choose the number of portions per feeding in the app. Press the lid button for an extra feeding when you are home. Use pellets no larger than 2 mm in diameter for reliable dispensing.

• The minimum portion is designed for small community fish.
• For a single betta, feed every other day rather than daily; overfeeding can cause bloating or death.

What pump and filtration are included?

The three-speed pump runs at 28 dB and offers low, medium and high flow settings. Low flow is 2 L/min (32 GPH) for bettas and shrimp; medium is 3 L/min (48 GPH) for guppies and tetras; high is 4 L/min (63 GPH) for goldfish or extra filtration. Two-stage filtration pairs a mechanical cartridge that catches debris with biological media that supports beneficial bacteria.

• Replace the mechanical filter cartridge every 3 months.
• Replace biological media every 6 months; never rinse it with tap water.

What comes with the tank, and what should I add?

The box contains the glass tank, smart lid with automatic feeder, full-spectrum LED, temperature display, quiet pump, mechanical filter cartridge, biological filter media, drain tube, setup guide and fish care card. Substrate, decor, fish, food and a heater are not included. Any adjustable heater works, and the Jengu 100W heater is compatible.

• The LED has South American, Brook, White, Night, Sunlight, Flowing and Aquarium modes.
• Set brightness and a timer; 4–6 hours of light daily is advised for healthy plant growth.
• The locking sealed lid helps keep curious cats out; the rimless glass provides an unobstructed view.
• A one-year warranty covers the tank and mainboard.

Jengu M1 suits first-time hobbyists, betta keepers and busy fish owners who want app scheduling, temperature alerts and the main aquarium components together. It is also designed for a few guppies, shrimp or snails, rather than an aquarium setup beyond its 5-gallon capacity. For a small home aquarium with automated feeding, adjustable flow and built-in lighting, the kit brings those functions together with a clearly defined set of care and compatibility requirements.
