Is a betta fish bony fish?

Yes, betta fish are bony fish. They belong to the order Perciformes, which is the largest order of fish, containing over 10,000 species. Bony fish are characterized by their possession of a bony skeleton, as opposed to the cartilaginous skeleton of cartilaginous fish such as sharks and rays. Betta fish have a relatively small, compressed body with a long, flowing tail fin. They are native to Southeast Asia, and are popular aquarium fish due to their beautiful colors and relatively easy care requirements.
