Built with high quality glass. All wiring is hidden in the column. Filter is extremely quiet.

Trickier to clean than other tanks, due to small opening provided. Heater not included.

Updated on 2016-12-03 – I’ve always been fond of the Fluval Edge because of its 3D cube design. Not only does it look amazing, your betta will have plenty of room to swim around in since the tank can hold 6 gallons of water, which is ample for bettas. Keep reading for our Fluval Edge 6 Gallon Review.

Fluval Edge 6 Gallon Features

  • 7600K high luminosity LED lighting

One of the best features is that most of the mechanics are hidden, which is a huge bonus for me. There is nothing worse that seeing a bunch of cables this way and that way. The filter that comes with the tank is more than sufficient to keep the aquarium clean for a longer period of time, which means a lot less maintenance for you. Another thing about the filter is that even though it does an excellent job at cleaning, it’s not too powerful for your betta. (Some pre-built kits come with filters that are way too strong for bettas, but that’s not the case here.)
Personally, the only big downside that I found with this tank (but not enough to dissuade me from getting it) is that when you do have to clean it, the smaller opening makes it a bit harder to clean. Aside from that, it would have been handy if Fluval had included a heater with the kit, but unfortunately it doesn’t so you will have to buy one separately. (Absolute must for bettas – see Importance of Having a Betta Fish Heater)

  1. Actually not a good tank for a betta, who needs to breathe oxygen from the top of the water. If filled properly, this tank has no air space at the top of the water.

    1. Thanks for the feedback Susan. Personally, I’ve never had any issues having bettas in this tank. Yes, the opening is a bit small, but as long as you baffle the filter, I don’t see any issues.
