Origin: The ancestors of this fish lived in Central America or Northern South America, but now they live in aquariums and ponds throughout the world.

These fish are also live in large ponds.

Behaviors: Peacock Bass can be aggressive and from time to time males have long energetic battles.

This fish will gulp down any fish that will fit into its mouth.

Water Conditions: These fish can adapt to many water conditions, and so as usual it's best not to try to change the pH or hardness.

Aquarium Size: when small a few Peacock Bass can live for a while in an aquarium with 30 to 60-gallons of water but will soon need a much bigger aquarium.

Eventually a single Peacock Bass will need a huge aquarium with at least 250-gallons of water.

An even bigger aquarium or pond will be better.

Decor: Most Peacock Bass eventually live in a pond or a bare aquarium with no gravel or plants.

Live plants are beautiful and improve the water quality, but Peacock Bass will usually rip plants up, so most aquariums with large Peacock Bass do not have rooted plants but sometimes do have floating plants.

Aquarium Filter: Bio-Wheel Filters are highly recommended for aquariums up to about 250-gallons.

A 30 to 60-gallon aquarium with one or two Penguin 350B Filters is a good home for a few small Peacock Bass.

But soon they'll need a much bigger aquarium with as many Penguin 350B Filters as will fit across the back.

Eventually they'll need an immense aquarium or large pond with a large powerful filtering system.
