It might be normal for a particular species of fish that is known to have white dots on their tails...
a fish with a yellow tail are the blue tang, yellow tail damsel, and that's all what know!!
The use of fish tail is that its help the Fish swim faster than its preadator. Like if the Shark was after a Fish than the fish wolud have to use its tail to swim faster than its preadator which is Shark.

stretch a normal gold fish tail
Purple with Red polka dots on its tail! Muahahaha
the goldfish that is being chased might be a female goldfish where as the others are male goldfish, so the female one gets battered around the tank and the fins and tail might shred it is a good idea to separate the single fish so it wont be attacked. i know this cause my Goldfish do the same XD Look for white dots on the cheek of fish that r chasing the other one. if it does have white dots its a Male hope that helped :)
No. I think you mean a thresher shark, which sometimes has a tail 10 feet long and stuns fish with it.
not sure the exact term of what its called, but it means your fish is about to give birth.
Well there are lots of types of fins for betta fish. my betta fish has a long stringy tail and fins, but my female has short average fins. most have plain fins. mine is the only one i have seen in my area with a stringy tail. most fish have stringy tails if they are sick but not mine he was bred to be like that. depending on the fish and the area well there are lots of things that are considered normal for bettas.
A clown fish has the normal parts most fish have, such as gills, scales, fins, a head, and body with tail. Its body also is covered with mucus that protects it from the sea anemone. The clownfish is orange in color and white large stripes.
If you are refering to a man/laboritory made "Glo-fish" then the species is the Zebra Danio and its' tail in a normal fish is about 3/8"ths. If it is one of the developed long finned types then it could be longer.
Having your goldfishes tail turn white could mean your goldfish is sick but it could also just be new tail growth.When goldfish grow new tail tissue it may appear white or grayish.This usually happens when a goldfish isn't fully grown .If it is new tail growth than it will be on the end and tips of the fish's tail not the whole tail.
