no the common fishes do but the special and specific fishes don't.
==============================================
No. Hagfishes and lampreys don't have any paired fins. Nor do spiny eels.
Some others are:
Order Gymnotiformes: South American knifefishes.
Family Syngnathidae: Sea horses and some pipefishes
Flabby whalefishes
yes
The ones in pairs are: pelvic fins and pectoral fins.
the fish looses its body balance
The paired fins (pectoral and pelvic) are the nearest things fish have to limbs.
The rohu fish typically has one dorsal fin, one caudal fin, two pelvic fins, and two pectoral fins, totaling six fins.
The flaps on a fish are called fins, which help the fish to maintain balance, steer, and move through water. There are different types of fins on a fish, such as dorsal fins, pectoral fins, pelvic fins, anal fins, and caudal fins.
There are two sets of "paired" fins. The ones on each side of the fish behind the gills are the "Pectoral Fins" and the ones in front of the fishes vent on the underside of the fish are the "Ventral Fins". Sometimes these fins are wrongly refered to as "Pelvic Fins".
A fish has several different types of fins. There are the pectoral fins, located beneath the operculum (gills). There is the pelvic fin, located at the bottom of the fish, below the pectoral fin. There is the anal fin, which i located behind the anus, and there is the dorsal fin as well. It is located on top of the fish.
They are on the Ventral side, but you probably mean the Pelvic fins and possibly anal fin, depending on the fish species These links provided below may help you :)
all fish have fins
The 5 types of fins found on fish are dorsal fins, caudal fins (tail fins), pectoral fins, pelvic fins, and anal fins. These fins serve various functions such as stability, propulsion, and steering in the water.
An abdominal fin is one of a pair of posterior fins in fish - the pelvic fin and the ventral fin.
