The Pictus Catfish (Pimelodus pictus) is a stunning South American catfish known for its long whisker-like barbels, energetic swimming behavior, and spotted body pattern. A highly active and fast swimmer, it adds excitement and movement to large aquariums.
Slender, silver body with distinctive black spots scattered across the body and fins. They have a forked tail and extraordinarily long barbels that can extend past the length of their bodies. Adults grow up to 4–5 inches, though some individuals may reach 6 inches.
8–10 years (with proper care)
Omnivorous; accepts sinking pellets, bloodworms, brine shrimp, tubifex worms, and other meaty live or frozen foods. Will also scavenge leftover food in the aquarium.
Pictus Catfish are among the most active and eye-catching catfish in the hobby. With their long barbels and spotted bodies, they are a delight to watch darting around the aquarium. They do best in groups and need large aquariums with open space and good water flow. While not the easiest fish due to their activity level and predatory nature, they are highly rewarding for aquarists who can provide the proper environment.
Intermediate (requires large tank, strong filtration, and careful tank mate selection).
55 gallons (75+ gallons preferred for groups)
6.0 to 7.5
4–15 dGH
74–80°F (23–27°C)
4–6 inches
Silver dollars, rainbowfish, medium barbs, peaceful cichlids (like Severums or Geophagus), and other medium-to-large community fish.
Very small fish such as neon tetras, guppies, or shrimp, as they may be eaten. Avoid aggressive large cichlids that may bully or injure them.
Pimelodus pictus
Pimelodidae
South America – Amazon and Orinoco River basins
Schooling; happiest in groups of 4 or more. Peaceful toward similarly sized tank mates but predatory toward very small fish.
Feed 1–2 times daily with a variety of sinking pellets, frozen bloodworms, brine shrimp, and tubifex worms. They are opportunistic feeders and will scavenge leftovers, helping keep the tank clean, but should not be relied upon as sole 'cleaners.'
pH: 6.0–7.5, Temperature: 74–80°F (23–27°C), Hardness: 4–15 dGH, Ammonia/Nitrite: 0 ppm, Nitrate: <20 ppm
Prone to ich, bacterial infections, and stress-related illnesses if kept in small tanks or poor water quality. Sensitive barbels can be damaged on rough substrate or sharp decorations.
Active, social, and peaceful when kept in groups. However, they are predatory by nature and may eat very small tank mates that fit into their mouths. Best kept in groups of 4–6 for confidence and natural schooling behavior.
The Pictus Catfish (Pimelodus pictus) is one of the most recognizable and sought-after catfish species in the aquarium hobby. Native to fast-flowing rivers in South America, particularly the Amazon and Orinoco basins, this species is admired for its sleek silver body adorned with black spots and extremely long, graceful barbels. These barbels help the fish sense its surroundings in murky waters. Pictus Catfish are highly energetic swimmers that often occupy the middle and lower regions of the aquarium, darting quickly across the tank. Due to their size, activity level, and predatory tendencies toward smaller fish, they are best suited for larger community tanks with robust, similarly sized species. They thrive in well-oxygenated aquariums with good water flow and plenty of open swimming space.
