About This

• 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. It sits on a desk, nightstand, bookshelf, or dorm shelf without crowding your space. 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, no green tint. High light transmission shows colors vivid and true-to-life, unlike standard glass that casts a green hue. The one-piece front panel has no center seam for a clean look. The 5mm glass has real weight and feels solid. A clear view from every angle.
• HIDDEN BACK CHAMBER, CLEAN FRONT VIEW - From your chair, all you see is fish. The black back chamber conceals the pump, filter media, and a heater compartment completely. No tubes, no wires, no equipment cluttering the front — just your fish and plants. The dark background helps shy bettas feel more secure and show brighter colors. The built-in lid holds the LED and 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.
• 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.
• JENGU SUPPORT – 1-Year Warranty Included. From setup and fish care to maintenance, we're here to answer your questions and help with any problem. From day one to a thriving tank, Jengu grows with you.
