No, fish are either born male or female and require the other to reproduce by germination. However, Some species like clown fish are all born male and later become female when there is no female present. Some other species are born female and later become female.

∙ 13y agoFemale fish lay eggs which are fertilised by males, so technically they do not "mate" but put them in the same tank and they will breed.

Sometimes, closely related fishes do interbreed and create hybrids, but it's rare.

No They are very different species and even if they attempted to mate, their eggs would be infertile.
How can you tell if your female Goldfish and your male Goldfish are going to mate.?
The male goldfish will get white spots on it's gill cover, and the female will start looking swollen because she has eggs inside her. Sadly though, most times when goldfish mate, they eat their eggs and you will get no young. If you try many times though it will probably work! Hope this helps!
When do the goldfish have the babies?
When they mate a few days after they will eggs. They tend to do this when it is about 70 degrees in the tank as it simulates spring when they would lay eggs in the wild.

No, since they are different species, the resulting eggs would not be fertile. They won't even (mechanically) fit together.

How do black moors reproduce?
Spring time is the breeding season for goldfish. During this time female goldfish will put on weight, and male goldfish will develop breeding tubercles (white dots on the head and gills). Goldfish may chase each other around the habitat in an effort to find a mate. When a male and female goldfish choose a mate the female will release her eggs onto the breeding ground (such as an aquatic plant, or breeding mop). The male goldfish will then release a cloud of Milt (sperm). The milt thus fertilizes the eggs, and goldfish fry begin to form within the eggs. The goldfish eggs will continue to develop for several days until they eventually hatch into fry. The fry will then grow into fully developed goldfish overtime. These goldfish will eventually reproduce, and thus continue the life cycle.
Can goldfish get mates?
yes, goldfish can mate, if you keep your goldfish in a pond... they usually mate in spring, and if you keep your goldfish in a tank, they may mate anytime... but they usually dont do this until they are 3 years old, when they mate, the male will get breeding tubercles which looks like pimples but not red, then they will do a chase, when the female get tired she will release her eggs and the male will fertilize them. of course, you can also try to find ways to make them breed though... anyways... as animals are... they can pretty much all breed including goldfish!
Can different kinds of crocodiles mate?
