How you can know when a goldfish is female or male or is pregnant?

Question

I have seven goldfish and I don't know what gender they are and one of them looks fat, and I think the fish is pregnant.

The type of goldfish I have is comet.

Answer 1

As goldfish mature, the males develop small white tubercules on the gill cover. Females do not.

As far as being "pregnant", many types of goldfish have a normally heavy body style. They are egglayers and if in good condition, the females will fill up with eggs periodically. If there is no male to spawn with, she will absorb the eggs back into her system.

You didn't mention what kind of goldfish you have, so there is no way to determine if the heaviness is due to eggs or just the natural body style.

Answer 2

if it is belly is bloated, it is NOT pregnant, goldfish lay eggs. it is much more likely that it is both constipated, or it is a fancy goldfish that appears like a golfball? what style of goldfish do you could have? if it appears bloated, speedy it for an afternoon or so, try to feed it a few cooked de-shelled pea (fishy laxative), and look ahead to bowel hobbies (sure, poopy!). if it is swimming is torpid or it can not relatively swim directly it's going to have built a swimbladder main issue, and if the scales seem raised, thats dropsy. neither of the ones matters are convenient to therapy and usually turn out to be being deadly. goldfish may also be rough to intercourse. and watching at a massive tummy isn't the way you intercourse them.

Answer 3

The female Goldfish are slightly bigger than the males and look even heavier in the abdomen when they are full of eggs.

* Male Goldfish develop white spots on their gills and pectoral called ?breeding tubercles? during spawning time.

* Males have midline ridges on their undersides beginning from the back of their pelvic fins and ending at their vent opening. This feature can be absent or smaller in females.

* Males have firm abdomen while in females; the area between the pelvic fins and the anal fins is more pliable.

* Male Goldfish have longer and pointed pectorals as well as stiff fin ray, while females have more rounded pectorals and shorter, finer front fin rays.

* Male goldfish have smaller and more oval anal openings and the anal fins are not as thick as that of the female goldfish who has a larger and rounder anal opening with a slight protrude. The anal fin is also thicker.

* The spawning time is the easiest time to distinguish the boys from the girls. The female opening will look larger and more swollen as the eggs begin to ripen. She would look big and heavier. Since fish reproduce through external fertilization, you can make out when a male is ready by the white breeding tubercles and you can actually push out the milt through his ventral opening by running a gentle finger along his sides.

* There is one more obvious, but kind of time taking way to make out which one of your fish is male and female. Find out who is chasing who ? the chaser will be the male and the chased and tired out one will be the female! It?s the natural tendency on part of the male goldfish to chase and nudge at a female?s rear part.

Answer 4

first of all they will never be pregnent since the gold fish are egg scatterers. When ready to breed you will know which is the male by seeing small white spots on the gill gover and head.

Answer 5

if the tail is long its a male. if it is fat and evn though it poos and doesnt get rid of it, then its pregnant
