i agree about the never having exercise, but you wouldn't have to change the water twice a day, as these sort of systems have a sump at the bottom and are constantly circulating the water. i have seen versions of this, but with larger individual tanks.God no, those 'cups' are even smaller than a quart jar you would use to jar young males as a breeder
Don't even think about just 'displaying' them in there, you would need to change their water twice a day and they would never have any exercise
