Scientific Name: The Blue Paradise Fish is scientifically known as Macropodus opercularis. This species is a variant of the more commonly known Paradise Fish, distinguished by its striking blue hues.

Water Quality and Temperature: To ensure the well-being of the Blue Paradise Fish, maintain the following water parameters:

• Temperature: Keep the water temperature between 70°F and 82°F (21°C to 28°C) to accommodate their wide range of tolerance.
• pH Level: The pH level should be maintained between 6.0 and 8.0, offering flexibility in different water conditions.
• GH Level: Aim for a general hardness (GH) level between 5 to 19 dGH, as this species can thrive in both soft and moderately hard water.
• KH Level: Maintain the carbonate hardness (KH) within the range of 4 to 12 dKH to help stabilize the pH levels.

Feeding: The Blue Paradise Fish is an omnivore with a diverse diet. Ensure a balanced diet by offering:

• Flake Foods: High-quality flake foods suitable for labyrinth fish.
• Pellets: Small pellets that are easy for them to consume.
• Live or Frozen Foods: Such as bloodworms, brine shrimp, and daphnia to provide essential proteins and mimic their natural diet.
• Vegetables: Occasionally include finely chopped vegetables like spinach or peas for added nutrients and fiber.

Tank Mates: The Blue Paradise Fish can be territorial, especially males, and may display aggression toward other fish. They are best kept with other semi-aggressive or similarly-sized species. Suitable tank mates include barbs, gouramis, and larger tetras. It’s advisable to avoid housing them with slow-moving or long-finned fish, as these may become targets of aggression. Additionally, keeping them with other Paradise Fish should be done cautiously, especially in smaller tanks, to avoid conflicts.

Substrates and Tank Decorations: Use a soft substrate, such as sand or smooth gravel, to create a comfortable environment for the Blue Paradise Fish. Decorate the tank with a mix of plants, rocks, and driftwood to provide hiding spots and establish territories. Floating plants are particularly beneficial, as they offer shade and create a more natural habitat, mimicking the fish’s native environments. Ensure that there is ample open space for swimming, as Paradise Fish are active and enjoy exploring their surroundings.

Suitable Plants: The Blue Paradise Fish thrives in a well-planted tank. Hardy plants like Java Fern, Anubias, and Water Wisteria are ideal choices, as they can withstand the fish’s occasional nibbling. Floating plants such as Duckweed or Frogbit are also recommended to diffuse light and create a serene, shaded environment.

Sexing: Sexing Blue Paradise Fish is relatively straightforward. Males are typically larger, with more vibrant colors and longer, flowing fins. Females are generally smaller and have shorter fins with less intense coloration. During the breeding season, males may also display more vivid colors and become more territorial.

Breeding: Breeding Blue Paradise Fish is relatively easy, even for novice aquarists. The male builds a bubble nest at the water’s surface, where he will entice the female to lay her eggs. After spawning, the male will guard the nest and care for the eggs. It’s advisable to remove the female after spawning to prevent aggression. The eggs will hatch in about 1 to 2 days, and the fry should be fed with infusoria or finely crushed flakes until they are large enough to consume more substantial foods.

Maximum Size and Longevity: The Blue Paradise Fish typically grows to about 3 to 4 inches (7 to 10 cm) in length. With proper care, these fish can live up to 6 to 8 years, making them a long-term companion in your aquarium.

General Information: The Blue Paradise Fish is a resilient and visually striking species, admired for its brilliant blue color and flowing fins. While they can be territorial, their hardy nature and adaptability make them a rewarding choice for aquarists who can provide a suitable environment.

A Fun Fact: The Blue Paradise Fish is one of the oldest species kept in the aquarium hobby, dating back to the 19th century. Its resilience and beauty have made it a popular choice among fishkeepers for over a century.
