Can Pictus Catfish Live with Goldfish?

Pictus catfish and goldfish have different temperatures and habitat requirements, which makes it generally not recommended to keep them together in the same tank.

Pictus Catfish prefer warmer water temperatures, around 72-82°F, while Goldfish prefer cooler water temperatures, around 65-75°F.

Additionally, Pictus Catfish are known to be active, fast swimmers and can grow up to 5-7 inches; while Goldfish are slower and more passive swimmers, Pictus catfish can grow larger and produce more waste.

This difference in behavior and size can lead to potential aggression and competition for resources within the tank.

Furthermore, Pictus Catfish are known to be carnivorous, and their diet can include smaller fish and invertebrates, so there is a risk that they may prey on smaller Goldfish.

Therefore, it is recommended to house Pictus Catfish with other compatible tropical fish species with similar environmental requirements and avoid keeping them with Goldfish. 

If you want to put catfish with Goldfish in the same tank, there are a few things to keep in mind to ensure that both species coexist peacefully.

  • Water temperature: Pictus catfish prefer slightly warmer water than Goldfish, so the ideal temperature for a tank with both species would be between 72-78°F.
  • Tank size: The tank should be large enough to accommodate both species comfortably. A 20-gallon tank is the minimum size for a single goldfish, so that a 40-gallon tank would be a good starting point for a tank with both pictus catfish and Goldfish.
  • Hiding places: Pictus catfish are nocturnal and enjoy hiding during the day. Provide plenty of hiding places in the bottom of the tank, such as rocks, driftwood, and caves.
  • Feeding: Both catfish and pictus catfish are omnivores, so that you can feed them various foods, such as flakes, pellets, and vegetables.
  • Monitoring: Keep an eye on both species to make sure they are getting along. If you notice any aggression, you may need to separate the fish.

With some care, pictus catfish and Goldfish can make happy tank mates.

Why You Should Not Put Pictus Catfish and Goldfish Together? (Expert Advice)

While pictus catfish and Goldfish may seem like compatible tank mates at first glance, there are several reasons why they should be kept separate.

Firstly, pictus catfish are nocturnal fish that prefer dimly lit environments, while Goldfish are diurnal fish that require bright light during the day. This difference in their light preferences can lead to stress and health problems for both species.

Secondly, pictus catfish are carnivores, while Goldfish are omnivores. This means that pictus catfish may view Goldfish as a potential food source, and there is a risk that they may attack and eat the Goldfish.

Finally, pictus catfish and Goldfish have different water temperature requirements. Pictus catfish prefer cooler water temperatures, while Goldfish prefer warmer water temperatures. Housing these two species together can lead to temperature fluctuations that can stress and harm both fish.

Can Pictus Catfish Eat a Goldfish?

Yes, pictus catfish can eat Goldfish. Pictus catfish are carnivores and will eat any fish in the tank that is small enough to fit in their mouths. Goldfish are a common prey item for pictus catfish in the wild.

Pictus catfish typically grow to be about 3-4 inches long, while Goldfish can grow to be 6-10 inches long. This means that pictus catfish will only be able to eat Goldfish that are smaller than them.

However, even small Goldfish can be a choking hazard for pictus catfish, and there is always a risk that they may injure themselves while trying to eat a goldfish. 

If you are considering keeping pictus catfish and Goldfish together, it is essential to consider the size of the Goldfish carefully. You should also ensure the tank is large enough to provide both species with plenty of space to swim and hide.

If you are concerned about the safety of your Goldfish, you should err on the side of caution and keep them in a separate tank.

Do catfish and Goldfish get along?

Yes, catfish and Goldfish can get along as long as the catfish species is peaceful and not too small. Some good catfish tank mates for Goldfish include Corydoras catfish and Otocinclus catfish.

What fish can live with Pictus catfish?

Pictus catfish are peaceful fish that can live with various other freshwater fish species. Some potential tank mates for pictus catfish include tetras, giant danios, Rasboras, and Gouramis. 

Can Pictus catfish be kept alone?

Pictus catfish can technically be kept alone, but they are a social species that thrive in groups of 3 or more. They will be more active and less likely to hide in a group.

Can Pictus catfish live with Oscars?

Pictus catfish can generally live with Oscars as long as the pictus catfish are large enough. Oscars are predatory fish that will eat anything that fits in their mouths, so small pictus catfish are at risk of being eaten. However, larger pictus catfish can usually defend themselves from Oscars. 

What to feed pictus catfish and Goldfish?

Pictus catfish and Goldfish thrive on a balanced diet of high-quality pellets or flakes formulated explicitly for their species. Include occasional treats like freeze-dried or live foods for variety.


In conclusion, caution should be exercised when it comes to housing pictus catfish and Goldfish together. While both species can thrive in similar water conditions, their differing needs and behaviors can pose challenges in a shared tank. Pictus catfish are more active and may outcompete slower-moving Goldfish for food. Additionally, Goldfish produce more waste, which can lead to water quality issues for the sensitive catfish. It’s best to provide separate tanks for each species to meet their needs. Can pictus catfish live with Goldfish? So, while pictus catfish can live with Goldfish, keeping them in separate setups for optimal health and happiness is generally recommended.
