Goldfish are probably among the best aquarium fishes that you would like. This resilient, interactive fish does not take much time to become the favorite of their masters.
You might like to look for the best mate for your goldfish. But it will not be a smart idea to just put any type of fish into that tank with your beloved goldfish. Finding the right partner for your goldfish can be a tricky one. In this article, we will give a complete idea about what fish can live with goldfish.
Here are the compatibility factors to remember.
To make sure you don’t mess up mixing fish with your goldfish, you need to look at some crucial factors. For ensuring better health and environment for your goldfish, you need to have a clear idea about these. It is not a hard nut to crack; just real research of your own is enough. As you have reached us, we will help you through it.
Goldfish are known as cold-water fish as they prefer to live in a temperature range of 65 to 75-degree Fahrenheit (18 to 24-degree Celsius). Now, most of the aquarium fishes we get to see are from the tropical region. There they live in a much warmer temperature of about 75-80 degrees Fahrenheit.
So keeping them with a goldfish in the same tank is not a great idea. If you are doing so, you are either keeping the goldfish in a warmer temperature or the other fish in a colder environment. This is not a healthy situation for your goldfish.
The warmer tank will force your goldfish to shred fat, thus cause health issues. If continued for the long term, this may stress them further and even make them die. So great attention is needed here in this factor.
Goldfish are thriving and always looking for food. By its omnivorous nature, it eats other fishes. So putting a smaller fish with it in the same tank might make your goldfish look for some snacks.
They eat a lot and will not hesitate to devour the smaller mate, no matter how long they have lived together.
Again, if the opposite happens, your goldfish might get eaten by the bigger fish in the tank. So it is always recommended to keep the same sized fish together. Also, goldfish itself need a lot of space to grow and live peacefully. Considering the tank size is also essential in this case.
The breed is also a matter of concern. Because if one grows faster than the other, there is always a chance for the smaller one to get eaten.
Well, there are two cases to focus on here. The first one is if you put a fish that’s slower or faster than the goldfish, the faster one will always get privilege while eating food because it will get to the food faster.
And secondly, the slower fish can be lunch for the faster one if their sizes do not match. So, keeping the same nature of fish with your Goldie will be a good step.
We all know that goldfish are peaceful. Some of them do not need any mate and like to stay being the “only child.” Putting an aggressive fish, for example, Betta in the same tank, can be hazardous for the goldfish.
The aggressive nature of the other fish can put your goldfish in stress and thus harm its health and growth. So it is better to keep fishes that are like the goldfish, loves to mind their own business. Otherwise, you can expect to see a beat-up, stressed goldfish, even dead in the worst-case scenario.
As now you know the factors to keep in mind while choosing a mate for your goldfish, now we can get started with the fish that can stay with goldfish.

Just a simple reminder, it is better not to keep the Zebra danios with the fancy breed goldfish. Fancy goldfish are too slow, and the danios are just the opposite. Being the faster one, the danios might have the lion share of the foods.

A great thing about this catfish is they are herbivores. They like to eat algae and other dead organic materials from the aquarium or tank. It reduces your maintenance issue. But you should not just let them live on the dead organic materials. Feed them regularly spirulina wafers, bloodworms, and other algae so that they don’t stay unfed.
Plecos are an excellent choice to put in the tank with your goldfish because they can adapt to different temperatures. Also, they are peaceful and friendly and are not likely to get into a fight. They can be big, so you need to have a large tank.
A couple of things to keep in mind while choosing Plecos. The normal breed of Plecos has a tendency of sucking the slime coat off the goldfish. So make sure you are putting Bristlenose Plecos with your Goldie. Also, they can get extremely territorial with another male. So consider not keeping two males together.

Again, the fancy breeds are not compatible with the familiar breeds. The fancy breeds are very slow in movement, whereas breeds like comet and shubunkins are incredibly fast and strong. They will have the upper hand while having the food, and it is not good for the fancy breed.
So keeping a goldfish with another goldfish can be a bit tricky. But if you have the main factors in mind, they are not a hard nut to crack.
