Pictus Catfish Tank Setup

Plan for at least 53 US gal min of water—that is the minimum in our database for a workable setup, not a challenge to crowd fish. Aim to hold 73–82°F and pH 6–7.5 without daily drama. These fish use the Bottom zone most, so put wood, plants, or open water there accordingly.

What Do Pictus Catfishs Eat?

We record diet as Omnivore (bottom feeder). Offer a few food types that match—dry, frozen, or gel—and swap now and then. One flake every day for a year is how dull color and gut trouble creep in.

Pictus Catfish Tank Mates

Temperament in the data: Peaceful. Treat small tank mates as potential snacks once the fish grows. SCALELESS - highly sensitive to medications and salt; use half-doses of any treatment. Will eat any fish small enough to fit in its mouth (neon tetra sized or smaller) - do not keep with nano fish. Needs groups of 3+ and a large tank (4ft+) due to active swimming.

Are Pictus Catfishs Good for Beginners?

We rate this as intermediate. Budget time for testing, maintenance, and watching behaviour if the water looks fine but the fish do not. If this would be your very first tank, start with something more forgiving and come back to this one.
