Stingrays

Stingrays are flat-bodied marine cartilaginous fish closely related to sharks, belonging to the subclass Elasmobranchii. They are characterized by their broad, wing-like pectoral fins and long, slender tails equipped with one or more venomous barbed spines. Stingrays are commonly found in shallow coastal waters, sandy lagoons, and reef environments. 

They are generally peaceful but require expert care, ample swimming space, and a diet of meaty foods such as shrimp and mollusks. Due to their size, sensitivity to water quality, and specialized care needs, stingrays are best suited for advanced aquarists with large marine systems.
