What Fish Can Go With Goldfish?

Goldfish are popular and beloved pets, known for their bright colors and lively personalities. If you have goldfish and are looking to add some companions to their tank, you may be wondering what fish can go well with them. While goldfish can be social and adaptable, there are some important factors to consider when choosing tankmates for them.

When selecting fish to live with goldfish, it’s essential to consider their compatibility in terms of water temperature, size, and behavior. Goldfish are best suited to live with other peaceful, coldwater fish that can thrive in similar environmental conditions. Additionally, it’s important to ensure that the tank is large enough to accommodate all the fish comfortably.

Factors to Consider When Choosing Tankmates for Goldfish

Before introducing any new fish to your goldfish tank, consider the following factors:

  • Water Temperature: Goldfish prefer cooler water temperatures, typically around 65-72°F (18-22°C). Therefore, it’s important to choose fish that can tolerate and thrive in the same temperature range.
  • Size Compatibility: Goldfish can grow quite large, so it’s crucial to choose tankmates that won’t be seen as a potential snack. Avoid fish that are small enough to fit into a goldfish’s mouth.
  • Behavior: Goldfish are generally peaceful and can coexist with other calm, non-aggressive fish species. Avoid aggressive or fin-nipping fish that may harm or stress out your goldfish.
  • Tank Size: Goldfish require a spacious tank due to their large size and high waste production. Ensure that the tank is large enough to accommodate the goldfish and any potential tankmates comfortably.

Now that you know the key factors to consider, let’s explore some popular fish that can make excellent companions for your goldfish.
