Marina CUBUS Glass Betta Kit

0.9 gallons is way too small of a space for a betta to be happy. Get a 5 gallon, heater, hood and light, and a betta hammock. Give him some plants (silk or real because pointy fake plants can injure him) and some gravel. Put a ghost shrimp or two in the tank with him to help keep his area clean. Then you have a happy betta. This tiny thing isn't the best choice.

As other reviewers have commented this tank is much too small to create a healthy environment for a Betta. While it is initially aesthetically pleasing the small size of this tank simply leads to stressed out fish, whom quickly loses their colour, and shortens their life span. If you're the kind of person whom values appearances over the health of your pets, than I doubt this review will change your mind. However if you genuinely care for the well being of your pets please select an alternative tank (Around 5 gallons, like the Fluval Chi).

This tank is entirely too small for a beta (or pretty much any fish, for that matter). These guys need at LEAST 5 gallons of swim space. A beta in a tank this small will get stressed out which greatly increases their susceptibility to disease, and ultimately, an untimely death. Do yourself a favor and buy a 5 gallon tank that costs less than this thing and enjoy your beta for much longer.

While other reviews have center mainly on the lack of space, size, etc of the Cubus, my case has been the reverse. I began with a larger tank for a double half-moon Betta male. His fins suffered continuously to the point that he stopped moving from the leaf and heater at the surface of the tank. He would just rest on them. He stopped swimming at all and began to look ragged. I had treated him for fungus, bacterial issues, and others thinking that was the cause of his fin state. No response.

I decided to get the Cubus because of it's gallon capacity and flat sides for easy visibility for him. A change was immediate! He would swim around, dive from the top to the bottom, actually rest at the bottom, and even make bubble nests. It seems that the tank preference would honestly amount to what the personality of the fish is. My boy is full finned and alert in this one and I can't be happier because of that.

I did opt not to use the LED light for the harshness it emitted. Instead I used that rectangle gap to act as an outlet line for his heater.
