For anyone doubting this is a real product, here is the active Indiegogo campaign page. The campaign starter is hoping to raise $10,000 to help fund his next “abnormal” aquarium concept by giving away these “upside aquariums” to people who contribute to his campaign, admitting these are small but are suitable for bettas and goldfish. Yikes!
Thankfully, there are no contributors at the time of this publication. We hope it remains that way.
Any fish in that would probably die in a day or two
