Goldfish are fin nippers.
Keeping goldfish and betta fish together will result in betta fish being nipped and suffering from issues.
Bettas have long colorful fins, and goldfish are fin nippers, which means goldfish will try to nip your betta fish fins.
Also, bettas are known to be short-tempered fish and will fight back with the goldfish.
So, whenever you plan to add a tankmate for your betta fish, go for fish that are not fin nippers.
Goldfish are omnivores and quick eaters.
Another important factor that stops us from keeping betta fish and goldfish together is their dietary requirements.
Betta fish are carnivore fish and require only meat-based food in their daily diet.

Goldfish are omnivore fish and require both meat and plant-based food in their daily diet.
Also, feeding betta-based food to a goldfish is not recommended, as this can make your goldfish suffer from issues like kidney failure, swim bladder disorder, and constipation.
Goldfish are quick eaters, meaning they will try to eat the food as soon as you add the food to the tank, resulting in your betta fish being hungry or goldfish being overfed.
Goldfish require a big-size tank to live.
Goldfish require more space to live comfortably.
Bettas require a tank size of 5 gallons and bigger. Keeping betta fish in a small size tank (Smaller than 5 gallons) will not let them swim and live comfortably.
When you plant to keep goldfish, you will need a much bigger tank, as goldfish require a tank size of 10-12 gallons.
So, with every addition to the number of goldfish, you will require an extra 12-gallon size to house them.
You can easily consider keeping them in a different tank as this way, you can provide them with their ideal living conditions, and they will live happily.
Goldfish produce lots of waste.
Goldfish are known to be dirty fish, which produce lots of waste.
Excessive waste in the tank will result in an ammonia spike which will cause ammonia poisoning in the tank.

Betta fish are very sensitive to ammonia, and even a small amount of ammonia in the tank can cause serious issues to betta fish.
So, it is not advisable to keep betta fish with a goldfish.

What are the compatible tankmates of my betta fish?
Whenever we visit the pet shop, we see that many of them, or almost every pet shop, keep betta fish separately in tiny containers or small bowls.
This way of keeping betta fish makes us think of two things:
- Bettas are meant to keep in small-size tanks.
- Bettas like to live alone on their own.
However, you must know that these two things are wrong.
Betta fish require ample space to live and swim comfortably.
Also, keeping them with their compatible tankmates will make them thrive.

You should add fish that are less colorful, non-aggressive, and smaller or similar to the size of your betta fish to your betta tank.
All these are the best tankmates of your betta fish:
- Feeder guppies
- Neon tetras
- Mystery snails
- Ghost shrimps
- Cory catfish
- Harlequin rasbora
- Ember tetras
- Clown plecos
- Kuhli loach
- African dwarf frogs
Conclusion:
Keeping betta fish and goldfish together in the same tank is not a good idea as they are not compatible with each other.
Bettas are warm-water fish, and goldfish require cooler water to thrive.
Goldfish are fin nippers and will try to nip at your bettas long flowing fin, which will cause aggression in your tank.
Also, they both have different dietary requirements, and it will be hard for you to feed them together.
So, all these factors stop us from keeping betta fish and goldfish together.
