Paracheirodon innesi (Neon Tetra)

The Neon Tetra (Paracheirodon innesi) is a popular and vibrant freshwater fish that is commonly kept in aquariums. Here are some key characteristics and information about Neon Tetras:

1. Appearance:

   • Neon Tetras are known for their striking and vibrant colors. They have a bright blue or turquoise stripe that runs horizontally along their body, starting from the nose and extending to the adipose fin.
   • Below the blue stripe, their body is a vibrant red color, creating a beautiful contrast.

2. Size:

   • Neon Tetras are small fish, typically reaching a size of about 1 to 1.5 inches (2.5 to 4 cm) in length.

3. Habitat:

   • Native to the blackwater streams in South America, Neon Tetras are found in regions like Brazil, Colombia, and Peru. These streams have soft, acidic water with dense vegetation.

4. Tank Requirements:

   • Neon Tetras are best kept in a well-established aquarium with stable water parameters. They thrive in slightly acidic to neutral water with a pH ranging from 6.0 to 7.0.
   • A densely planted tank with subdued lighting and hiding spots is ideal for Neon Tetras.

5. Diet:

   • Neon Tetras are omnivores and accept a variety of foods. They typically eat small live or frozen foods like daphnia, brine shrimp, and micro-pellets.
   • A balanced diet contributes to their health and enhances their coloration.

6. Behavior:

   • Neon Tetras are peaceful and schooling fish. They feel more secure and display their best colors when kept in groups of at least six or more.
   • They coexist well with other non-aggressive community fish.

7. Breeding:

   • Breeding Neon Tetras can be challenging due to their specific requirements. Soft, acidic water and the right environmental conditions are crucial for successful breeding.
   • Females are slightly rounder, and during breeding, they scatter adhesive eggs. Providing fine-leaved plants for the eggs to adhere to can increase the chances of survival.

8. Common Issues:

   • Neon Tetras are susceptible to some common aquarium diseases, such as Ich (white spot disease) and fin rot. Maintaining good water quality and a stress-free environment helps prevent these issues.

Remember that proper care and attention to their habitat, diet, and social needs are essential for keeping Neon Tetras healthy and vibrant in a home aquarium.
