Pacu fish will devour nearly anything in your fish tank since their human-like teeth enable them to crush anything. As a result, you can provide them a pellet diet or frozen foods. Pacus may also devour small fish in fish aquariums.

This implies you should exercise caution while selecting tank mates for them. Flakes comprise a significant percentage of the meals of pacus throughout their juvenile stages. As they mature, these pacu fish should preferably be fed a combination of quality pellets and blood worms, as well as the occasional worm.

However, you should avoid overfeeding the fish with worms and shrimp, as these have been proved to make them finicky eaters.

Some pet owners choose to feed their pacus live goldfish. These are commonly available and affordable, and to the majority of people, they may appear to be a wonderful idea.

Pacus, as some of the largest Amazon fish, requires a considerable amount of food and frequently feeds in multiple “bite events”. Each event consists of many bites, similar to how piranhas feed. To replicate these eating patterns in your fish tank, feed pacu fish mutiple multiple times every day.
