Yes, I bought this one before I knew that bettas need more space, because of its looks - and I thought it was "nice and big" compared to some of the other betta tanks they had!
I think it may be a little more than 1.5 g but it's certainly less than 2. It's a good sturdy glass tank which I use for small fish (like right now I have a tiny male in there) or temporary use. It is a nice-looking tank, I like the LED light and wish I could fit it on different tanks when I'm not using the cube.
I've tried heating it with a 10 w non-adjustable heater, but it gets too hot. You have to use an adjustable heater as the temperature fluctuates otherwise.
