A dark streak running along each side of the body and a slightly golden area on the side of the head behind the eye help to distinguish this tiny catfish. The body is otherwise sufficiently transparent to allow the green eggs in the female’s reproductive tract to be visible prior to spawning.
Many pimelodid catfish are solitary by nature. They are predatory and grow to a large size, demanding an extensive area in which to hunt. However, a number of smaller species, including the Pictus Catfish (Pimelodus pictus) shown here, will associate in groups and can be kept together more easily in the home aquarium.
