Pictus Catfish Full Grown: Size, Appearance, Price & More

The Pictus catfish is one of the most popular freshwater aquarium fish species in the world. As it matures, its appearance and habits change quite a bit from when it is young.

Today, we'll take an in-depth look at what to expect from a fully grown Pictus catfish and how to care for one at that stage.

Size at Full Grown

When fully grown, Pictus catfish can reach up to 6-8 inches (15-20 cm) in length. Their bodies tend to elongate and become more streamlined as they mature. Females usually grow a bit larger than males on average.

Weight at Full Grown

Healthy, full-grown Pictus catfish typically weigh between 5-12 ounces (150-350 grams). Diet and water conditions play a big role in their overall weight and condition.

Appearance at Full Grown

As Pictus catfish reach adulthood, their coloring becomes more vibrant and pronounced. Their yellow-and-black spotted pattern is very distinct. Spots cover their entire body and may become larger. Males can develop tubercles (breeding bumps) on their anal fins and barbels (whiskers) during breeding season.

Personality at Full Grown

Adult Pictus catfish tend to be more bold and active swimmers compared to juveniles. They enjoy exploring tank decorations and foraging along the substrate. However, they are still generally peaceful community fish as long as kept with non-aggressive tankmates of similar size.

Price

Mature Pictus catfish command a higher price than juveniles due to their larger size. Expect to pay $10-15 each for healthy, full-sized individuals from your local fish store or online aquarium shops.

Food/Feeding

At full size, Pictus catfish have larger appetites than younger ones. Feed them 2-3 times daily. Offer a varied diet including processed flakes/pellets designed for bottom feeders, algae wafers, bloodworms, brine shrimp, and vegetables like zucchini and cooked spinach.

Lifespan

With excellent care, Pictus catfish can live 5-7 years on average as an adult. Top-quality water conditions and a stable environment help maximize their longevity.

Health at Full Grown

Some health issues may arise in mature Pictus catfish if conditions are subpar. Monitor for signs of intestinal blockages, infections, fin erosion/damage from aggressive tankmates, and parasites. Quarantine new additions. Maintaining pristine water is a must for adults.

Care and Nutritional Needs at Full Grown

• House in at least a 20-gallon tank alone or with other peaceful species
• Perform partial water changes 1-2 times weekly to dilute waste
• Maintain water parameters of pH 6.0-7.5, temperature 72-82°F, and low nitrates
• Provide hiding spots and flow from a filter/air stone
• Supplement quality protein, vitamins, and minerals 1-2 times weekly
• Vacuum gravel thoroughly during water changes

Costing

Expect to budget roughly $100-150 per year for a mature Pictus catfish. This accounts for its food, any medication/treatment if needed, tank maintenance supplies like filters and substrate replacement, and water quality testing kits.

Possible Behavioral Changes of a Fully Grown

Adult Pictus catfish typically become bolder as they mature. They may be more active swimmers that forage along the bottom and explore the tank. Breeding males may establish territories and charge at reflected images. Otherwise, mature Pictus catfish continue exhibiting peaceful community fish behavior.

Notable Characteristics of a Fully Grown

To summarize, some standout attributes of the fully grown Pictus catfish include: vibrant spotted coloring, elongate torpedo-like bodies up to 8", bold and active demeanor, breeding tubercles/barbels on males, larger food intake needs, higher veterinary costs, and longer average 5-7 year lifespans with optimal care.

Final Thoughts

The Pictus catfish makes an enjoyable freshwater community fish even at maturity. Just be sure to select tankmates appropriately for an adult's larger size and more assertive nature compared to juveniles. With a sufficient tank, high-quality food variety, and diligent water maintenance, Pictus catfish thrive for many years as a beautiful centerpiece of any aquarium.
