If you could keep a prehistoric species as a aquarium pet, what kind would you want to keep and what size tank do you think it would require? I'm a big fan of Dunkleosteus, but with it being around the size of a great white shark it would need 5-10 million gallons of water. A smaller option would be trilobites, they look super cool and come in varying sizes.



Though... you will find errors in my post. Just waiting for somebody to point them out. Sorry if I made any of you amateur or professional paleontologists cringe. Like asking ad disc golfer what kind of frisbee they use.
