Invertebrates 

The term invertebrate is a very, very broad term that encompasses about 97% of the world’s animal species. The term simply means that the animal or organism that lives without a spine or a vertebral column. Instead of a calcium-based hardened spine, an invertebrate sometimes uses an exoskeleton as main axial support. And this is evident in marine invertebrates like clams, crabs, lobsters, scallops, sea urchins, shrimps, snails, and starfishes. However, the term invertebrate can also be applied to such animals like anemones, fan worms, sea cucumbers, and sea slugs – or those species that do not have a spine and the exoskeleton.  

Fish keepers and salt water enthusiasts are finding unbridled pleasure in maintaining marine invertebrates in their keep. It is, of course, quite unusual to see such sea-faring animals being comfortable in someone’s aquatic tank or aquarium. However, the primary challenge that most experienced fish hobbyists have to face when it comes to the care of these marine invertebrates is to create an actual set-up that will allow the animals to thrive successfully. These animals are of course, salt water species that need adequate lighting and special feed. Under the right circumstances, marine invertebrates can thrive and open up a whole new dimension in the world of fish keeping.
