Feed 1–2 times daily with cichlid pellets as the staple. Supplement with shrimp, earthworms, crickets, and frozen foods.
Egg layer; forms bonded pairs, cleans flat surfaces for egg-laying, and both parents guard the fry.
Breeding Electric Blue Oscars follows the same process as other Oscars. A bonded pair requires at least 100 gallons. The female lays hundreds of eggs on cleaned surfaces, and both parents guard them until hatching in 2–3 days. Fry can be raised on infusoria, baby brine shrimp, and crushed flakes.

Hole-in-the-head disease, ich, fin rot, and obesity. Prevent with varied diet, clean water, and avoiding feeder fish.
Semi-aggressive; territorial but social with humans. Can coexist with other large fish in spacious tanks.
Curious, interactive, and intelligent. They enjoy rearranging tank decorations and may display territorial aggression. Very engaging with human interaction, often begging for food and following movement outside the tank.
Electric Blue Oscars are an eye-catching variant of Astronotus ocellatus, bred for their brilliant blue hues. Unlike the darker Black or traditional Tiger Oscars, the Electric Blue variety glows under aquarium lighting with shades of turquoise, sky blue, and metallic sheen. Native Oscars originate from the Amazon Basin, but this morph is selectively bred in captivity. They are intelligent, interactive, and often compared to aquatic pets for their ability to recognize their owners. Due to their large size and heavy waste production, they require strong filtration and frequent water changes. Their bold and curious nature makes them rewarding, but their semi-aggressive temperament demands careful tank mate selection.
