Pacu

Pacus are primarily herbivorous and frugivorous, requiring a diet rich in plant matter, fruits, and nuts. Feed high-quality vegetable pellets, blanched vegetables (spinach, zucchini, peas), and occasional fruits (apples, bananas) once daily. Supplement with occasional protein sources like earthworms or bloodworms, but prioritize plant-based foods to prevent digestive issues and maintain their natural feeding behavior.

Pacus are intelligent, curious fish that become semi-aggressive as they mature, particularly during feeding times and territorial disputes. They are active mid-water swimmers that require substantial space to roam and exhibit complex social hierarchies. Juveniles may seem docile but develop increasingly aggressive tendencies with age, making them unsuitable for community tanks despite their peaceful appearance when young.

Breeding Pacus in captivity is extremely difficult and rarely successful in private aquariums. They require massive tank volumes (1000+ gallons), specific seasonal temperature fluctuations, and precise water conditions to trigger spawning. Successful breeding is primarily limited to large public aquariums and commercial facilities with specialized breeding programs.
