how can u tell if a fish is a male or female?

Answer 1

if it gives birth then it female
else male
but mostly there are many fishes that can be identified

Answer 2

depends on species. some fish are sexually dimorphic ( diff. colors) such as with african cichlid KENYI's where the female is blue and the male is yellow. Also with africans on the anal fin the males will have what is called egg spots. With other species of fish sometimes the shape of the anal fin will distingish sexes for example with the livebearing platy fish the male will have a pointy anal fin whereas the female will have a rounded anal fin other fish that are sexed this way are angelfish, green severums,and paradise gouramis. With mollys sexing is done by the top dorsal fin. ON the female it is rounded and short in length, where as the males is longer in length and height. Some fish can only be sexed by the shape of their anal Vent, this would take some effort to have a way to magnify the area to see. Other species can not be properly sexed until they are near to or full size like oscars cichlids and goldfish.

Answer 3

Depends on the fish. Livebearers have a difference in the anal fin. Bettas look very different. Usually, female fish are smaller/drabber looking. It's the males that have to attract the females. Goldfish look almost the same, but have a difference in the anal fin too. Do some research on your fish, and you can usually tell.

Answer 4

For tropical fresh water fish. U have to look at the "fins" under their tails. Females' fins are like small triangles; males' are like thin, pointy needles. Most of the time, females have bigger bellies. Females are the ones that are being chased everywhere, males are the ones that are chasing them.

Answer 5

I had a fantail Goldfish called Dave once. I knew he was male because he dragged his tackle around the tank like a sea-anchor.

The obvious way to get around the problem is to buy a fish you know is male and if you end up with lots of pheeesh, you know the one you have is female. Then you can crumble up the pill into its tank and stop the little ho' reproducing.

Answer 6

It depends on the fish. Some like bettas are easy. Live bearers only require a quick look at their fins. Others well only the fish know. What sort of fish is it?

Answer 7

If it has a lot of headaches,large mouth and moans a lot my husband reckons it must be female but truthfully in the majority of temperatepond fish,notably goldfish and koi,the sexesare quite similar to each other,especially outside the breeding season.Even so,males are generally slimmer than femalesand possess a stronger,often rough-edged,first pectoral (chest)fin spine

Answer 8

Yes it does depend on the species of fish. Colour, size, body shape, fin and tail shapes and general markings are the most common differentiating characteristics. But can't answer specifically without knowing species except in some cases genus is good enough.

Answer 9

It depends upon what type of fish it is. Some fish like guppies are easy to tell. Other fish you can't tell unless it's mating season and they change colors. You need to add in the details what type of fish you are talking about.

Answer 10

well it depends on what fish it is, some fish are hard to sex but some tropical fish are very easy to sex for example if its a guppy then they are really easy the males are bright coloured and you can see their penis and with the femails they just have a fin same with platties and many more, gold fish are harded to sex

Answer 11

depens on whot sort of fish ie the male tench has visibly larger fins than the female
