how can I tell a male fish from a female fish?

Question

Ihave two fantailedgold fish,one of which is an ornimentalgoldfish,onceI put the two of them toghether and the smaller one kept on ramming the other one between its fantail.,I dont know if this was its way of saying get lost or your bed or mine?what gives here?

Answer 1

Female goldfish have a vent that sticks out slightly. Males have tubercles on their gills when they are ready to mate. There is no other way of telling goldfish apart, no fin shape or anything like that. If the fish are less than 3 inches than they likely are too young for breeding.

Answer 2

it's hard but most female fish have a bigger stomach and the males just have slim body. When a fish is young there is no way you can find out until it's an adult so just wait and see.

Answer 3

The easiest fish you can differintiate between male or female is the sword tail. The mail has the sword tail and the female doesnt.

Answer 4

theres a simple way of going to a fish store and asking or buying a male/female fish and put it in the tank and see if they mate

Answer 5

The males are smaller and more colorful, this is true with fish, birds, lots of animals.

Answer 6

male goldfish will chase female goldfish. if a female isn't around they will chase another male goldfish. kind of like guys in prison. male goldfish get little pimples on their gills when they are ready to mate (just like humans) females get these weird little ducts that are harder to see. it is easy to spot a male through the chasing behavior. but just because its being chased doesn't mean its a female.

Answer 7

like with humans the one with their mouth always moving is the female

Answer 8

males also tend to be just slightly more agressive.
