A fish's fins have many functions. Fish have several fins, and what they do with them depends on their species. Some fins are used purely for decoration or to attract a mate, but most have more practical functions. Generally, the fish's tail (caudal fin) is used for propulsion and steering.
The dorsal fin can be used to control height in the water and steering.
The fins on the sides of the body are used to balance the fish, for propulsion, for steering and paddling.
The pectoral fins on the fish's underside are used for steering.
The anal fin in the male livebearer is modified for use during internal fertilisation - it becomes a penis-like organ called a gonopodium.
provides stability and helps during turns. Sometimes (if spiny or containing poison) it is used for defense.
The anal fin is primarily used as a stabilizer; for females it is usually for show but for males it holds their reproductive part and they usually move it during mating season
The anal fin helps a fish to stabilize themselves in the water.
