The Red Tail Giant Gourami is a large, hardy freshwater fish known for its vibrant red fins, which become more prominent as it matures. These "gentle giants," scientifically named Osphronemus laticlavius, can grow to over 20 inches (50 cm) and are prized for their personable and intelligent nature, though they require a very large aquarium to thrive.
Physical description
Size: Can reach lengths of over 20 inches (50 cm).
Fins: Develop striking red caudal (tail) and dorsal (back) fins as they mature, which is where they get their name.
Body: Has a deep, compressed body shape and develops a more "beak-like" face and a swollen forehead with age.
Scientific name: Osphronemus laticlavius.
Behavior and temperament
Personality: Often described as "gentle giants" that are personable and intelligent, sometimes recognizing their owners.
Social: While generally peaceful, adult fish can become territorial, especially in smaller tanks or when breeding.
Breathing: They are obligate air-breathers, meaning they must be able to surface for air.
Intelligence: They are considered one of the ultimate "pet fish" due to their intelligence and long lifespan, with some living for over 20 years.
Care and habitat
Aquarium: Due to their large size, they need a very large tank, with a minimum of 100 gallons recommended for a single fish, and even larger tanks are necessary for multiple fish or other large tankmates.
Diet: They are omnivores that will readily accept a wide variety of foods, including treats like fruit, but in the wild, they eat algae, crustaceans, frogs, and fish.
Tank setup: The aquarium should include plenty of plants, rocks, and driftwood to provide hiding spots and mimic their natural environment.
Water parameters: Ideal temperature is between
75−82∘F (24−28∘C), and a pH of 6.5−7.5 is recommended.
