Red Cobra Guppy Tank Size and Setup

When setting up an aquarium for Red Cobra Guppies, it’s important to consider their social and active nature. Here are some guidelines for tank size and setup:

Tank Size: Red Cobra Guppies are relatively small, so a 10-gallon tank can comfortably accommodate a small community of them. However, if you plan to keep a larger group or want to include other fish, consider a larger tank.

Filtration: Adequate filtration is essential to maintain water quality. Red Cobra Guppies are sensitive to changes in water conditions, so invest in a good-quality filter.

Decoration: Provide hiding spots and plants, both live and artificial, for them to explore and seek refuge. Floating plants are especially appreciated, as they help diffuse the light and provide a sense of security.

Substrate: Use a fine gravel substrate to mimic their natural environment and facilitate the growth of live plants.

Red Cobra Guppy Feeding

Red Cobra Guppies are omnivorous and have relatively simple dietary requirements. To maintain their vibrant colors and overall health, provide a well-balanced diet that includes:

  • High-quality Flakes or Pellets: A staple of their diet, these should contain essential nutrients and vitamins.
  • Live or Frozen Foods: Treat them with live or frozen foods like daphnia, brine shrimp, and bloodworms to add variety and ensure they receive essential proteins.
  • Vegetable Matter: Guppies also benefit from plant matter like spirulina flakes and blanched vegetables.

Feed them in small portions a few times a day, ensuring they consume their meal within 2-3 minutes to prevent overfeeding.

Red Cobra Guppy Diseases, Treatment, and Prevention

Red Cobra Guppies are generally hardy but can still be susceptible to common aquarium fish diseases. Here are some diseases to watch out for and how to prevent and treat them:

Common Diseases:

  1. Ich (White Spot Disease): This parasitic infection presents as white spots on the fish’s body. Isolate infected fish and treat them with an appropriate medication.
  2. Fin Rot: Caused by bacterial infection, it leads to tattered fins. Maintain good water quality, and consider antibiotic treatment.


  • Maintain stable water conditions.
  • Quarantine new fish before introducing them to the main tank.
  • Avoid overfeeding, as uneaten food can lead to water quality issues.

Red Cobra Guppy Tank Mates

Choosing suitable tank mates for Red Cobra Guppies is essential for a peaceful and harmonious community aquarium. They are generally peaceful and get along with various fish species, including:

  • Tetras: Neon tetras and cardinal tetras are colorful and peaceful companions.
  • Corydoras Catfish: These bottom-dwelling fish help keep the tank clean.
  • Mollies: Mollies share similar water parameter requirements with guppies and make good tank mates.

Avoid aggressive or fin-nipping species that may harass your Red Cobra Guppies.

Red Cobra Guppy Breeding

One of the exciting aspects of keeping Red Cobra Guppies is their prolific breeding behavior. If you wish to breed them, here are some key points to consider:

  • Separation: Place pregnant females in a separate breeding tank to protect the fry from being eaten by adult fish.
  • Fry Care: Once the female gives birth, move her back to the main tank and ensure the fry have plenty of hiding spots to avoid being preyed upon.
  • Feeding Fry: Provide finely crushed flakes and baby brine shrimp for the young fry. As they grow, gradually transition to regular guppy food.

Red Cobra Guppies are known for their beautiful offspring, which may display varying degrees of the signature red and black colors.

Red Cobra Guppy Plants

Adding live plants to your Red Cobra Guppy aquarium not only enhances the aesthetics but also provides several benefits:

  • Oxygenation: Plants help oxygenate the water during photosynthesis, creating a healthier environment for your fish.
  • Aesthetic Appeal: Live plants create a natural and visually pleasing habitat, mimicking their native environment.
  • Hiding Spots: Guppies, especially fry, use plants as hiding spots and shelter from more aggressive tank mates.

Consider easy-to-maintain species like Java fern, Anubias, and Vallisneria, as they thrive in guppy-friendly conditions.

In conclusion, Red Cobra Guppies are a captivating addition to any freshwater aquarium. With their remarkable appearance, straightforward care requirements, and prolific breeding behavior, they are suitable for both beginners and experienced aquarists. By maintaining the right water parameters, providing proper nutrition, and offering a suitable environment, you can enjoy the beauty and charm of these stunning fish for years to come.
