It is possible to find a suitable tank mate for a goldfish, but you can’t just add any species!
There are some very important things to keep in mind.
First, any fish added to the tank has to thrive in the same environment as goldfish, especially in water temperatures from 65 or F to 75 or F.
As most importantly, fish have to get along. What exactly does that mean?
Some things: The new fish won’t damage the goldfish, the goldfish won’t be able to eat the new fish, and the goldfish will still have the space it needs to grow.
What fish can live with Goldfish?
If you’re thinking of adding tankmates to live with your goldfish, there are some really cool options. These fish can thrive in a similar qualifying environment and can live alongside the goldfish in peace.
8 List of goldfish tank positionings
1. Other goldfish
Adding another goldfish of the same size and variety is one of the easiest ways to add another fish to your goldfish tank.
Just remember that the goldfish is omnivorous and can be predatory. It is important that the tank mates are evenly paired.
Be very careful with the size. The big goldfish will eat the minors so they must be the same size.
In addition, extravagant goldfish tend to move slower than the commons and probably won’t be able to compete for food.
2. White Cloud Mountain minnows
The main reason why white mountain fish Cloud is a good fit with Goldfish is that they are cold-water fish that will do well in the same environment as goldfish.
They are fish education and do not do well on their own, so you will have to add at least 3, although 6 is better.
White Cloud Mountain fish are also very fast and can usually outperform the goldfish which makes them less likely to become prey.
3. Rosy Barbs
Rosy Barbs as the same type of water as goldfish. They also grow to be capable of 4 to 6 inches long so they are a good match of size, too.
They are not aggressive fish and will leave their goldfish alone and are too big for their goldfish to eat.
Keep in mind that pink spikes are the school of fish and get very stressed, either alone without sex or in small groups. They must be kept in groups of at least 6.
4. Rubber and Bristlenose noogies
Either a rubber nose Pleco or bristles make big tank mates for a Goldfish. The noogies are quiet fish that will usually leave your goldfish alone.
They spend most of the day eating algae from rock and grass, which also helps keep your tank clean.
Stay away from common Plecos, as there are reports that you have a habit of sucking the golden fish slime coat.
5. Time or Loaches Dojo
Time Loaches, or Dojo Loaches, are another great option because they are cold-water fish that thrive in the same kind of environment.
These loaches should be kept in groups of 3 or more and enjoy the burrow, so make sure they are supplied with fine gravel or sand casting.
Wolves also require a lot of their own space, so you’ll need a very large tank to shelter them with goldfish.
