Paskai Rainbowfish – The Fiery Gem of Nano Aquariums

If you're looking to add vibrant color and lively personality to your freshwater tank, the Paskai Rainbowfish, also known as the Red Neon Rainbowfish or Paska’s Dwarf Rainbowfish, is a showstopper. With their glowing red bodies and shimmering blue highlights, these nano-sized fish are a favorite among aquascapers and community tank enthusiasts.

? Origin and Habitat

Paskai Rainbowfish are native to Papua New Guinea, where they are found in slow-moving streams and densely planted waters. Like many rainbowfish, they thrive in clear, well-oxygenated environments with plenty of aquatic vegetation.

Despite their wild origins, they are hardy and adaptable, making them excellent candidates for home aquariums—especially in peaceful community or nano tank setups.

? Appearance

Paskai Rainbowfish are small in size—usually reaching about 1.2 to 1.5 inches in length—but their bold coloration makes them stand out. Males display a stunning fiery red to orange coloration with iridescent blue or neon stripes along their bodies, especially under good lighting conditions. Females are slightly duller but still attractive.

Their compact size and vibrant hues make them perfect for aquascapes, especially those with dark substrates or contrasting green plants.

? Aquarium Requirements

• Tank Size: Minimum 10 gallons for a small group

• Temperature: 72–80°F

• pH: 6.5–7.5

• Water Hardness: Soft to moderately hard

• Lighting: Moderate to high lighting will enhance their colors

• Aquascape: Dense planting with open swimming space; floating plants are a bonus

Paskai Rainbowfish are very active and social, so a group of at least 6 is recommended to encourage natural schooling behavior and reduce stress.

?️ Diet and Feeding

These rainbowfish are omnivores and thrive on a varied diet:

• Micro pellets or quality flake food

• Frozen or live daphnia and baby brine shrimp

• Occasional treats like bloodworms (chopped) or cyclops

Feeding them a protein-rich diet helps maintain their vibrant colors and supports overall health.

? Temperament and Tank Mates

Paskai Rainbowfish are peaceful and energetic, making them ideal for community tanks with similarly sized and non-aggressive tank mates.

Compatible tank mates include:

• Chili Rasboras

• Ember Tetras

• Celestial Pearl Danios

• Corydoras (especially dwarf species)

• Shrimp (with caution—they may nibble on baby shrimp)

• Other peaceful nano fish

Avoid housing them with fin-nippers or large fish that might view them as food.

? Breeding

Breeding Paskai Rainbowfish is relatively straightforward:

• Use a well-planted tank with soft, slightly acidic water

• Condition the fish with high-quality, protein-rich foods

• Males will display vibrant colors and perform courtship dances

• Eggs are usually deposited on mosses or fine-leaved plants

If you want to raise fry, it's best to move eggs to a separate tank. Fry can be fed infusoria or powdered fry food, eventually transitioning to baby brine shrimp.

? Why Choose the Paskai Rainbowfish?

• Vibrant, unique coloration perfect for nano tanks

• Peaceful and social—great for community aquariums

• Hardy and beginner-friendly

• Fun to breed for hobbyists wanting a rewarding project
