It is best not to put invertebrates in a tank with the common porcupine fish
as there is a chance it might find them appetizing. It may eat shrimps, small crabs,
or mussels out of your hand - but watch out for its teeth! Sadly, this fish is sometimes
sold, dried and bloated, as a decorative object, or even as a lampshade! It can
grow to 90 cm in the wild.
