The Fluval Flex 2.0 is a 9-gallon curved-glass aquarium kit with a rear three-stage filter, an RGB plus white LED light on a remote, and dual adjustable output nozzles. The filtration is built into the back of the tank, so the display stays clean, and the honeycomb print hides the waterline and filter area. It suits a first freshwater setup or a small planted tank on a desk or counter. Against basic glass-tank kits it adds remote-controlled lighting and a spray bar, but the heater is sold separately and the 9-gallon size limits you to small fish and shrimp.

Owners of the Flex line generally like the clean look and the hidden rear filtration, and the remote light is a common talking point. Complaints center on the pump noise on some units and on the small volume limiting what you can keep.
The Fluval Flex 2.0 is a 9-gallon freshwater aquarium kit with a curved front glass panel. The glass has a honeycomb print that conceals the waterline and the filtration area. The tank has a modern style and is made for indoor use.
The kit includes RGB + White LED lighting (6500–7000K) with a remote control for color blends, dynamic effects and mood settings. The light is meant to bring out fish colors and support live plant growth. A rear 3-stage filtration system combines a foam block, a Poly-Carb cartridge and BioMax media for mechanical, chemical and biological filtration.
Two output nozzles adjust independently to shape water movement, and a spray bar gives a gentler, even flow. The hinged cover gives easy access and has a feeding port. A channel organizes the power cord, and rubberized stabilizers keep the pump quiet. A heater is sold separately (A781 or 14880).
