    • Fluval 9 Gallon fishtank just the right size!
This 9 gallon tank is just the right size for a night stand or end table. The filters are hidden behind the rear wall plate allowing easy access when performing your weekly maintenance routine. The lid contains a colorful array of LED lights that also utilize the moon cloud cover and storm effects that can be controlled with a remote control. A heater is also a necessity which can be positioned in the pump chamber. Although not required or recommended I do a complete water change every week. I have had most of my Tetra, Catfish and Molleys over 1 year utilizing this method. Thanks Steve ... show more

    • Very Nice Little 9 Gallon Tank
I first wanted the 15 gallon version of this tank, but settled for the 9 gallon, which fit perfect on a stand I have. I'm using this tank more for aquascaping than for fish, which I may add after a couple of months. I have had this tank for a couple of weeks and it looks really nice! I removed the lid and replaced with an after market light, as the included light did not work well for my timing needs. Plus I really did not want a lid covering the aquascape. The included filtration works well for this small tank. You will have to purchase a heater, as this tank does not come with one. Plus I added a CO2 system to get my pants growing and this has worked great. The clarity of the task is good and has a curved front glass, which curves outward which is where the "Flex" in the name comes from. This gives the tank a nice look and does not detract from the viewing of the tank at all. ... show more

    • Great 9 gallon tank
Review Image by R. Mitchell
Fluval knows what's up. Very easy to work in, comes with everything except a heater. I really like this tank. The flow from the default nozzles are a bit strong so I 3D printed a new nozzle to distribute the flow better without as much turbulence.

    • Best small tank ever!!!
Review Image by P. Michael Moffa
I received this 9 gallon tank as a Christmas gift and absolutely love it. The lift up opening on the lid allows you to feed the fish without lifting the lid. The compartments in the rear for the heater, ploycarb filter and pump makes the tank free of all this and more attractive. I had a fluval edge prior to this, but this is superior. ... show more
