How big does a pictus catfish get?

A pictus catfish (Pimelodus pictus) reaches about 5.0 inches as an adult. Plan tank size and tank mates around the adult size, not the small fish you buy at the store.

Tank size & setup

Give a pictus catfish a minimum of 55 gallons, with water at 75–81°F and a pH of 6.5–7.5. Keep them in groups of at least 3 — they are shoaling fish and become stressed and washed-out alone. As a moderate-care, carnivore species, a stable, cycled tank with the right diet keeps them healthiest.

Good tank mates

Pair a pictus catfish with peaceful species that share its temperature and pH range. Compatible options include:

About the pictus catfish

Pimelodus pictus, also known as the pictus cat or pictus catfish, is a small member of the catfish family Pimelodidae, native to the Amazon and Orinoco river basins and commonly kept as a pet in freshwater aquariums. Pictus catfish are sometimes mislabeled as Angelicus cats in the aquarium trade, but the latter name actually refers to an unrelated African catfish, the mochokid Synodontis angelica.

FAQ

What size tank does a pictus catfish need?
At least 55 gallons. Because they shoal, budget for a group of 3+ rather than a single fish. Bigger is always more forgiving for water quality.
Is the pictus catfish good for beginners?
It's a moderate-care species, so dial in a stable, cycled tank and correct water parameters first.
