Peacock bass fish care

They are beautiful fish that can be found in the deep waters of Florida. They require a different level of care than some other types of fish and need an environment with plenty of oxygen. Because they come from deep water, peacock bass fish can usually only be found at aquariums or pet stores that specialize in freshwater fish.

They can be a little bit more expensive than some other types of fish because they require special care. In order to have the healthiest peacock bass fish, an aquarium needs good filtration and plenty of oxygen in the water. A heated filter is best for this type of tropical fish because it will provide them with a comfortable environment and keep the water at a consistent temperature.

What they eat

The diet of peacock bass fish should consist mostly of live food, such as worms, crickets, and small fish. It is important to avoid feeding them too much-processed food because it can be harmful to their health. They will also enjoy some vegetables in their diets, such as spinach or lettuce leaves.

Tank mates

Peacock bass fish can be kept in a community tank with other fish that are of similar size and temperament. Some good tank mates include other types of bass, eels, catfish, and loaches.

Make sure to avoid keeping them with any aggressive or territorial fish, as they may cause problems for the fish. Also, avoid keeping them with fish that are too small, as they might become food.

Peacock bass fish can also be kept in a species-only tank if there is enough space for each individual to have their own territory. However, it should still only house one male peacock bass per aquarium because males will show aggression towards other males of the same species.

Water conditions

The water temperature for peacock bass fish should be around 75-80 degrees Fahrenheit, with a pH of about neutral. They prefer slightly acidic water, so it is important to avoid adding too much baking soda to the tank.

The water level in the tank should be at least 18 inches deep, as these fish like to swim in open waters.

Make sure the water is well-oxygenated, as the fish are not very tolerant of low levels of dissolved oxygen.

The tank should have a cover with an opening at one end to create a dry area for them to rest in between swims. The gravel on the bottom should be dark and coarse so they can camouflage themselves when necessary.

Peacock bass fish can be quite difficult to breed in an aquarium environment because they prefer a free-swimming area. They will eat their own larvae, so it is usually necessary to remove the parents after spawning and raise the offspring by themselves if one wants any peacock bass fish for future generations of fish.

If there are enough hiding places in the tank, it is possible to keep males and females together for breeding purposes.

The female will lay her eggs in the gravel at the bottom of an aquarium, where they can be easily collected before hatching. Make sure to clean out any unhatched or uneaten eggs after three days so they do not become infested with parasites that can kill the fry.

The newly hatched fry will need to be fed a diet of brine shrimp, plankton, and powdered food until they are large enough to eat other types of food.


Peacock bass fish can live up to 15 years in the wild, making them long-lived fish. In captivity, they have been known to reach 20 years old or more.

Parasites and diseases

Peacock bass fish are prone to parasites. If you keep them in an aquarium with live plants, chances are that they will host ich or velvet worms at some point.

When purchasing your fish from a breeder, be sure to ask the seller about any recorded history of illnesses and what types of medication were used on the fish before purchase.

Peacock bass fish are also susceptible to a variety of diseases, so it is important to keep an eye on them for any signs of sickness. If you notice your peacocks are not behaving normally or have developed lesions or parasites, take them to a qualified fish vet as soon as possible.


They have a few natural predators in the wild, chief among them being largemouth bass. Other predators include alligators, caymans, otters, and herons.
