How to find the gender/sex of the fish?

Question

Well i have read about how fish reproduce but i have'nt herd about how to find the sex / gender of any domestic fish?

Answer 1

Right on for PeeTee, different species differentiate gender by many different factors, and there really isn't one specific aspect across the board. Some species, there is almost little difference between the two. Some are very easy. Most Gourami are fairly easy to tell apart. The males in general, have a longer dorsal fin, and are more slim. A female will have a round shorter dorsal fin, and be round in the mid section. Arowana's however are almost impossible to tell just by eye a male and female. For most fish, if you know what you have, doing a goggle search should have a fact/data sheet on the web about them, and you'd look for sexing or gender idenitity to tell.

Livebearers, like mollies, platies, guppies, and swordtails are the easiest to sex. Look at the anal fin, right below the belly. If the fin shoots straight back like a stick, it's a male. If it hangs down like a flag, it's a female.

Other species are a little more difficult. Some have cues such as color (some cichlids), length of whiskers (angelfish), or spots on their anal fin (some cichlids). For those it's best to just read up on the specific species to sex each individual.

Also, if you are breeding fish, you should have AT LEAST 2 females for every male (except in some cichlid species where they pair up very easily). This reduces the stress placed on the females during mating through something called a dilution effect. This means that the male can only spend so much of his energy chasing one female at a time when others are present, which gives them a chance to rest and recooperate. Also, females tend to aggregate (group together) to protect each other when a male is around.

Answer 3

The best possible answer I can give you is Google *fish* Sexing, but put the name of the fish (betta, gold, Barbs) because each kind of fish has differnt typs of set off points.

On one kind the male can be larger and brighter
the other kind can have a male as the small one, so with out an exact fish I can not be of better help

Answer 4

Most male fish look different from females. For instance male bettas are bigger and have longer tail fins and are more colorful while the females are smaller have short fins and aren't as colorful as the males. Another breed would be the mollys their fins are different. So really the only way to sex fish is by apperance!

Answer 5

It's different for each species and some are determined only by con-specifics or surgery. There are clues,like fin shapes and body size,but each requires a working knowledge of the individual species. In other words,you gotta study.

Answer 6

Depends on the fish.... Mollies and guppies are easy to figure out...goldfish and neons are more difficult.

Neons the stripes are different in sex's, one is straighter and the other

Guppies and Mollies the lower fins are different

Answer 7

depends on the fish, but mainly, the males have brighter colors, and more slender slimmer body than the females...

on livebearers such as platies, females are absolutely bigger; while males are slimmer, and possesses a sexual fin called gonopodium that shaped like a needle.

guppies are also very easy to distinguish, aside from their gonopodiums, males have BIG colourful tailfins while females look normal..

on dwarf gouramis, males are colourful, with those orange colorations and dots and stuff, females are kinda like plain silver...

bettas are easy to sex, males are a bit bigger than females, and hey have BIG fins with big varieties, females' fins are plain... yes male bettas are colourful - until some farmers developed colourful females too...

from how they act, males are usually more aggresive, they are more likely to e territorrial... females are much calmer...

well, hoped that helped you... good luck
