I've always wondered and perhaps you can answer- with those fully enclosed glass spheres you can buy with fish in them... what happens when the fish breed? Doesn't it get overcrowded quickly?

The fully enclosed spheres contain Hawaiian red volcano shrimp, not fish. They don't breed because they require extremely specific breeding conditions (highly saline water and geothermal activity) so eventually the shrimp die out. However these shrimp live for ages so they can theoretically last up to 10+ years!
