Semi-aggressive; territorial, especially when breeding.
Provide pellets as a staple diet, with frozen/live foods for variety. Avoid feeder fish to prevent disease.
Egg layer; forms pairs, lays eggs on flat surfaces, and protects fry diligently.
Breeding is similar to standard Oscars. They lay hundreds of eggs that hatch in 2–3 days, with fry guarded by both parents.

Hole-in-the-head disease, ich, fin rot (more common due to long fins), and parasites.

Playful, curious, and interactive with keepers. Like other Oscars, they rearrange tank décor and may act aggressively during feeding or spawning.
Long-Fin Oscars are an elegant variation of Astronotus ocellatus, bred for their elongated, flowing fins that add a graceful touch to their naturally bold presence. They retain the intelligence, interactivity, and personality of standard Oscars while offering a unique aesthetic appeal. Due to their longer fins, they may be slightly more vulnerable to fin damage, so care should be taken with aggressive tank mates. Long-Fin Oscars need spacious tanks with strong filtration due to their size and waste production.
