Oscar - Red

Oscar fish (Astronotus ocellatus) are large, highly intelligent South American cichlids renowned for their dog-like personalities, vibrant color variations, and strong owner recognition. Often referred to as "water dogs," these fascinating creatures require dedicated care due to their size and significant waste production.

Key Profile Facts

• Scientific Name: Astronotus ocellatus (common variants include Tiger, Red, and Albino Oscars).
• Size & Lifespan: Grow 12 to 15 inches long and live 10 to 15 years.
• Temperament: Semi-aggressive, territorial, and known to playfully or angrily rearrange tank decorations.

  A minimum of 55 to 75 gallons is recommended for a single adult. For multiple fish, larger setups (125+ gallons) are required.

• Water Parameters:
  Maintain a temperature of 74°F to 80°F (23°C to 27°C) with a pH level between 6.5 and 7.5.

• Filtration:

• Tank Mates:
  Best kept alone or with other large, robust species (such as large plecos or other sturdy cichlids) that won't fit in their mouths.

Oscar fish are a captivating addition to any aquarium, but they demand proper care and attention to thrive. Their intelligence and unique personality make them a favorite among dedicated aquarists.
