HOMLUX - 3.5 Gallon Fish Tank Aquarium Smart Arch Clear GPPS 3 Color Self Cleaning - Black

Featuring graceful curved arched facade made of high-clarity durable GPPS plastic that resists daily scratch and accidental impact, this 3.5-gallon mid-size desktop smart aquarium balances proper breeding space and compact placement advantage with mature built-in self-cleaning circulating purification system. Three-selectable LED light colors replicate natural sunlight variation to benefit small tropical fish physiological activities and elevate ornamental display effect for home desktop decoration in bedroom, study and home office scenarios. The optimized silent circulating pump drives full tank water circulation continuously to send waste into hidden rear filter compartment for layered purification, cultivating helpful nitrifying bacteria to keep water transparent steadily and slash frequent manual water changing troubles for novice aquarists with limited spare time. Its moderate 3.5-gallon capacity offers enough living space for multiple small ornamental fish without occupying excessive desktop area, coming pre-assembled with core functional parts for instant use right after water filling and pet stocking.
