Lince Catfish (Platynematichthys notatus)

Lince Catfish

The Lince Catfish is a sleek, predatory freshwater species prized for its striking appearance and active behavior. Known for its elongated body, subtle patterning, and alert personality, this catfish brings both elegance and intensity to large aquariums. Best suited for experienced aquarists, the Lince Catfish thrives in well-maintained environments with plenty of swimming space and secure hiding spots.

Diet

Lince Catfish are carnivorous predators. In captivity, they should be fed a varied diet including:

• High-quality sinking carnivore pellets
• Frozen foods (bloodworms, shrimp, silversides)
• Live foods (feeder fish, worms — use sparingly and responsibly)

A protein-rich diet is essential for proper growth and health.

Tank Mates

Due to their predatory nature, tank mates must be chosen carefully:

• Avoid: Small fish (will be eaten), slow or delicate species

Always ensure tank mates are too large to be considered prey and can handle similar water conditions.
