Not True. You can only tell when the fish mature which is about 1 years old. When fish begin to breed their sex organs become visible. the female has a v shape and the male has a u shape. the females sex organ is bigger, but usually the male is bigger than female
The male has longer more elaborate fins and brighter color
There are several species of "marine" fish that are commonly called "Angelfish" but there is no knowledge yet of how to differentiate between the sexes or breed any of them. They are all regarded as very difficult to keep alive and so they are only recommended to be kept by very experienced aquarists who have specialised in Marine fish for some considerable time.
The most pronounced difference between the male and female angelfish is the size of the tube located between the anal and the ventral fin. This tube will be much thicker in the female than in the male, but the difference is generally not easily visible until the fish have begun to spawn.
It's all in the tail. the males is larger and longer and the females is shorter.
A girl Betta is dull and not as pretty as the male. But, a boy Betta is colorful and pretty to attract the female mate.
you can tell if its a boy or girl by the fins the male Betta has long fins and the female Betta has small fins
Yes.
yes
can you tell if a fish is a boy or girl by the tail
No, they are fighting fish. They will kill each other no matter what sex they are.
No, they can live alone or with other female bettas. They might bite each other but won't kill.
A female betta has very small fins with a long body while the male betta have lots of nice flowing fins.
no one
you can tell by the dots or spots on the boy fish and on the girl is just a gold fish colres
Boys have more colors than girls....THE PRETTIER ONE
