One of my readers asked me a question ” How To Tell If My Goldfish Are Pregnant” and I decided to write a post about this. Many people often get very interested in goldfish breeding and wonder are my goldfish pregnant and are there going to be little baby goldfish. What people first need to realize is that goldfish don’t become pregnant. Goldfish are not livebearers, meaning that they don’t have live young. Goldfish are called egg layers meaning that when goldfish breed during the spawning process eggs are released and fertilized by the male and then the eggs hatch into young fry a few days later. Seeing goldfish breed is very neat and interesting to see the whole process in motion.
So goldfish don’t become pregnant but you can tell the differences between males and female goldfish by viewing them from above. In order to tell when and if your goldfish will breed involves proper planning, recording temperatures, sexually mature goldfish and knowing when the eggs are ready and matured inside the female goldfish. The eggs need to be fully developed and ready in order for successful breeding to occur.
If you want to learn more about goldfish breeding visit some other posts I’ve made on breeding and raising young goldfish.

How often do goldfish lay eggs?
I HAVE A VERY FAT LOOKING GOLDFISH. MAYBE IT IS FEMALE, I DO NOT KNOW. BUT I SEEM TO NOTICE THAT "SHE" STAYS IN ONE SPOT MOST OF THE TIME AFTER I FEED THEM. I HAVE A LOT OF GOLDFISH, AND THEY ARE ALL IN ONE TANK. ANYWAY, I HOPE YOU CAN ANSWER MY QUESTION. WHY IS SHE STAYING IN ONE SPOT AND NOT MOVING AROUND LIKE THE REST? I JUST BOUGHT HER FROM THE PET SHOP SO I AM NOT SURE IF SHE HAS EGGS OR WHAT. I AM JUST CURIOUS ABOUT THE WAY SHE BEHAVES. I HOPE SHE IS NOT HAVING EGGS BECAUSE I DO NOT KNOW HOW TO BREED THEM ACTUALLY!
THANKS A LOT AND MORE POWER TO YOU!
Paulette,
You can see more information on your goldfish question below:

Goldfish breed basically 2-3 times a year.

About your fat goldfish you will need to first find out the gender or your goldfish. Your goldfish could very well be a female goldfish that could be full of eggs.
You did mention one fact that concerns me a little. You said you have a lot of goldfish in one fish tank. This could be the reason that your goldfish is resting in one spot. Your water quality could be poor and I suspect high ammonia, and nitrite would could be the reason your goldfish is ill or becoming sick.
Please check your water quality in your aquarium right away or your other goldfish may be in jeapordy.
Thanks,

I HAVE 5 FISH IN MY 10 GALLON FISH TANK. I SAW THEM CHASING EACH OTHER AND I JUMPED ON THE COMPUTER TO FIND OUT WHAT THIS MEANT. I WENT ON YOUR SITE AND READ ALL OF YOUR ARTICLES. BUT I AM STILL NOT SURE IF MY FISH ARE GIRL/BOY AND IF THEY ARE BREEDING! IF SO WHAT SHOUT I DO? PLEASE HELP ME!
to figure out if your goldfish is a girl or boy. If your fish is all orange its a male. If its white and orange its a female hope this helps
How do u know when a fish is pregnant? How do they act?
Goldfish do not become pregnant as they do not give birth to live young. Goldfish lay eggs in which they normally hatch within 72 hours. When goldfish are ready to breed you will start see them corting or chasing in your pond or aquarium. The goldfish doing the chasing is the male and the one being chased is the female. Hope this answers your goldfish question.
I have heard that other goldfish will eat goldfish eggs…any truth to this?
