Query: Nothing can survive

Betta require atleast one gallon to be happy and healthy. This grossly over-price piece of crap only holds a quarter of that. This means that your betta would slowly die of ammonia build up and burns. If some how the ammonia and the ills it causes didn't kill your betta it'd likely start eating itself out of boredom.Besides a betta can not even move in the thing, if you want your betta that motionless, just get a picture or statue of a betta instead.
