How do you determine sex in tetra fish?

Answer 1

The females tend to be chubbier and the males have a very tiny hook on their anal fin. I very much doubt if you will be able to breed Neon Tetras. It is a very difficult thing to do even for experts.

Answer 2

With most breeds of fish, the female has short fins and tail while the male's are much longer. This is true with tetras, goldfish, guppies, mollies, and most other fresh water aquarium fish. Yes, the goldfish on Pinnoccio was actually male. That is why Disney does more research now.

Answer 3

how i know is the male is very pretty and has long fins and the female is a brownish color with short fins

Answer 4

The male tetras are usually more slender while the females have a more rounded belly, other then that it's pretty hard to tell.

Answer 5

Well the male has big beautiful long fins and the female has small short fins

Answer 6

The gender of a neon tetra is determined by the body shape of the fish. Females have a much deeper body than the males, meaning their bellies are slightly bigger.

Answer 7

Normally the male betta fish has much longer flowing fins than the female.

Answer 8

the males are bigger than the females

Answer 9

If you take it out of the water and fart on it the male will live and the female will die
