When a fighter fish, or betta fish, has bigger fins, it often indicates better health and genetic quality. Larger fins can enhance their appearance, making them more attractive to potential mates, which is crucial in their natural breeding behaviors. Additionally, bigger fins may help them display dominance in territorial disputes with other fish. However, excessive fin size can also make them more susceptible to injury and disease if not properly cared for.
Well, if you mean a Siamese fighting fish (betta splendens) the male are always bigger than the females, and usually the males are more colorful. The males have large tails, as the femaleshave small tails and dorsal 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.
I guess you mean "Anal fin". If so, the answer is "yes fish do have an anal fin."
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 :)
To swim..? If you mean the fin on top of their bodies then it helps stabilize them.
It means that something ripped their tails or fins, most likely the teeth of another fish.
The most common Asian style fish that people get tattoos of are the Koi fish. Koi fish tattoos symbolize good fortune.
If you mean "crawfish", then the answer would be bigger fish like catfish.
Although I'm not sure what you mean by "deep" body, Betta fish, or Siamese Fighting Fish, or Rumble Fish (if you're S.E. Hinton) are thin, brightly-colored (domestically bred males tend to be more colorful), and have long, wavy fins.
Bettas are slow retiring fish. They do not move around much normally. Silvery coloured "pectoral fins" are quite common.
Male betta fish tend to be very aggressive. They are best alone unless theres a special type of specie they can get along with. They like to have personal space. And as using fighter fish you probably refer to Siamese fighting fish which is betta fish
If you mean like a Siamese fighting fish or beta fish they are like.. size of a ordinary goldfish I think and can be many colors but the fins are long and wavy it's a very elegant fish but still has the intend to kill another fish. But these are only the males. The females brownish maybe goldish. Not as flowy on the fins and looks for like a goldfish. ;)
