They are goldfish, a type of carassius auratus, a species of carp.
It's important to use the correct terminology when talking about animals to avoid confusion and ensure accurate information.
Now, to answer your question, goldfish can live with other fish, but there are important considerations to make:
Factors to Consider:
* Tank size: Goldfish need plenty of space, especially as they grow. Smaller species, like the common goldfish, require a minimum of 10 gallons per fish, while larger goldfish need even more space.
* Water temperature: Different species have different temperature preferences. Goldfish prefer cooler water (68-72°F), while some tropical fish require warmer temperatures.
* Aggression: Some fish are more aggressive than others. It's important to choose tank mates that are compatible in terms of temperament.
* Feeding habits: Some fish are omnivores, while others are herbivores or carnivores. Make sure the diet you choose is suitable for all the fish in the tank.
* Disease: Introducing new fish to a tank can increase the risk of disease. Quarantine any new fish for a few weeks before adding them to your established tank.
Fish that can be good tank mates for goldfish:
* Other goldfish: Goldfish can be social animals, and they can often live happily with other goldfish of similar size.
* Loaches: Some loaches, like the Kuhli loach and the Yasuhikotakia sidthimunki, are peaceful and can be kept with goldfish.
* Snails: Snails can help keep the tank clean and provide a different type of company for goldfish.
* Shrimp: Some types of shrimp, like ghost shrimp and cherry shrimp, can be peaceful tank mates for goldfish.
Fish that are not good tank mates for goldfish:
* Aggressive fish: Avoid fish known for their aggression, such as cichlids and certain barbs.
* Tropical fish: Goldfish prefer cooler water than most tropical fish.
* Small fish: Goldfish can be clumsy and might accidentally injure smaller fish.
Remember:
Always research the specific needs of any fish you are considering for your tank. Consult with a knowledgeable fish expert or veterinarian to ensure you are providing your goldfish with a healthy and happy environment.
