I believe certain cichlid do
Yes a parrot fish female could turn into a parrot fish male it changes gender and color :}
Yes it is true. If the dominant female dies the dominant male will change sex and become the next dominant female.
Quite a lot of fish are Hermaphrodites, they can switch their sex as they mature and become breeding stock.
I own both male and female.
One way to sex a tropical fish is to observe a mature male or female. The female will eventually lay eggs and the male will show his penis if a mature female is around.The way to sex a tropical oscar fish is to simply observe whether or not the female lays eggs. It is not possible to tell by just looking at the fish.
Clownfish, wrasses, moray eels and other fish species are known to change sex including reproductive functions. A school of clownfish is always built into a hierarchy with a Female fish at the top. When she dies, the most dominant male changes sex and takes her place.[2] In the wrasses (Family Labridae), sex change is from female to male, with the largest female of the harem changing into a male and taking over the harem upon his disappearance.
A female or male goldfish can be any colour. The colour of the fish does not determine the sex of the fish.
As a star fish he technically has no sex (as in male/female)
yes it does change its sex A clown fish changes it's sex according to rank... A female clown fish is the largest fish in the colony and has the highest rank. Then a dominate male is next, and the the next 4 or 5 non-breeding males follow in rank.... It is believed that each fish drop 20% in size as the ranks decline. This is probably to prevent any altercations... As a female dies off the highest ranking male will become a female and the 2nd highest male will now become the highest ranking male and becomes the breeding male for the colony... And this continuses throughout the colony on and on and on.... Hope this helps!!
There are so many species of fish and they all differ. There are some in which there appear to be no differences and others that are so different they look like different species. If you define the species then I may be able to tell you how to sex them.
No. Betta fish will attack each other no matter the sex.
No animal that is female can fertilize a female. Some animals are hermaphrodites, ie, male and female at the same time. Others, such as clownfish, can change sex. However, at the time of fertilization one clownfish would be male and the other female.
