Fish tank? Pish posh. I desire a desktop tank full of jelly-like invertebrates, thank you very much, which is why I’m currently desiring this tank full of tiny Medusozoa something fierce. Yes, that’d be jellyfish to the layperson.
If this aquarium doesn’t qualify as green innovation, then I don’t know what does. Because using a small garden to filter out nitrates from your freshwater fish tank is pretty damn eco-conscious.
Wouldn’t it be nice, while waiting for the bus, to have an aquarium full of fish to look at? At least for those first few days, until they die, at which point it’d get depressing.
