What paired and unpaired fins do fish have and what functions do these organs perform?

The fish have two pairs of paired fins; these include the pectoral and pelvic fins. The rest of the fins are the dorsal, caudal, and anal fins and are unpaired. The tail provides the fish with forward movement, has the function of a motor, the anal and dorsal fins are needed to balance the fish in the water. The pectoral fins are used by the fish when moving in a weak current or at low speed, they also, like the pelvic fins, help the fish to maintain balance. Some fish move along the bottom of the reservoir by means of their pectoral fins. The more developed the fins in fish, the more calm waters it lives and vice versa.
