How To Tell If Your Goldfish Is Pregnant

Goldfish do not give birth to their young ones alive; hence they are not livebearers. Instead, they lay eggs that will remain outside their body until they hatch. Until these eggs hatch, they aren’t free-swimming fish.

How to tell if your goldfish is pregnant is quite simple; however, it is one of the essential knowledge aquarists that have goldfish in their tank should have. This awareness will help you make preliminary plans for the coming fry, as well as take care of the pregnant fish.

Here are five practical ways that you can tell if your goldfish is pregnant.

Chubby or Protruded Stomach: Once you notice the belly of your female goldfish is protruded or unusually chubby, it might be an indication that they are pregnant. The protruded belly usually has a plump and gravid look.

It is, however, essential to know that protruded belly is different from the swollen belly. Swollen belly can indicate that the fish is sick. Likewise, you can be sure that the protruded belly is not as a result of too much food by observing them for a few days.

Release Of Eggs When They Are Picked Up: If you regularly observe or assess your goldfish, it will be easier to know when they are pregnant. If your goldfish is pregnant, you might find some eggs coming out a goldfish wiggle around your hand. This sign is one of the best ways to identify if your goldfish is pregnant affirmatively. It can also indicate that the goldfish has many eggs, and it is on the verge of spawning.

Getting Chased Around The Tank By Other Goldfish: Firstly, it is essential not to confuse this sign with bullying. If the goldfish is only chased around by other species of fish, then it is more likely to be bullying rather than pregnancy. However, in the case of pregnancy, chasing around usually occurs when female goldfish are on the verge of releasing eggs.

They alert other fish by releasing a particular pheromone to the tank. The male goldfish on getting the alert will chase the female firmly from behind while trying to nudge her beneath her stomach. This nudging will make the females release the eggs for the females to fertilize.

Aerial Observation Of Goldfish: The aerial view of a goldfish can provide you with insights about whether they are pregnant or not. If you observe a loopier and rounder belly when you view the goldfish from above, then you can suspect pregnancy in your goldfish.

However, it is not advisable to confirm the goldfish pregnancy only with this observation. You should look out for other signs and behaviors to confirm the pregnancy.

Tubercles In Male Goldfish: Yes, you read that right. You can get a deep insight into the pregnancy of female goldfish from the male. Males also show some peculiar signs during spawning.

The most prominent of these signs is the showing of breeding tubercles on their pectoral fins and gill covers. If you have multiple males in the tank, the tubercle on one or more males can help you tell that one of the females is in her spawning season.

Suitable Tank Conditions For Goldfish Breeding 

The first element you need to ensure the smooth, comfortable, and successful breeding of your goldfish is a good tank. The size of the container should be spacious enough to accommodate two adult goldfish.

Likewise, you should configure the water and tank conditions to suit pregnant goldfish. One of the configurations is to ensure that you have a proper cycle and stable parameters in the tank.

The inclusion of plants in the breeding tank can also be of enormous advantage. Aside from the fact that it provides the pregnant goldfish with hiding places, it also gives them surfaces to lay their eggs during spawning.

Another crucial factor to take into serious consideration is the temperature of the tank. You might need a slight variation from the regular goldfish tank and water temperature. The optimum temperature for goldfish during breeding and spawning season is usually 20°C.

However, they can still cope in a temperature range of 18-26°C as long as all other factors are in place. Once your goldfish are ready to mate, the slow but steady rise in the water temperature will further alert them about the breeding season.

Finally, it is essential to protect pregnant goldfish from stress; therefore, you should keep them away from bullying fish. In case you are housing just goldfish in your tank, you should ensure that you keep the right male to female ratio.

Preferably, you can keep goldfish breeding partners in a different tank through the breeding season.

Conclusion 

Goldfish are one of the most natural fish to keep in the aquarium when it comes to caring demands. However, they might require little more attention as soon as they get pregnant. You should start by optimizing and stabilizing the water and tank conditions.

Also, you should keep them with only suitable tank mates or appropriate male to female ratio. You should also protect them from stress while supplying them with the essential nutrients
