For the LumaTank they chose betta fish because "They can live at room temperature without a heater, aerator, or filter."
Poor bettas! This is the second time that I have seen a betta tank on Kickstarter described like this.
You'd think they'd be more careful after the jellyfish tank fiasco...
the update seems to imply things are better though. I wonder how much of the issues with the jellyfish tank was people just not being capable of maintenance. also, if your jellyfish keep getting stuck on the rocks... remove the rocks, remove some of them?
It's a common misconception that betta thrive in those environments. unfortunately a lot of them survive living like that. we just know better
