Scientific Name: The Silver Perch is scientifically classified as Bidyanus bidyanus.

Water Quality and Temperature:

• Temperature: Maintain a water temperature between 68°F to 78°F (20°C to 26°C) for optimal health and growth.
• pH Level: Aim for a pH level of 6.5 to 7.5, which closely reflects their natural habitat in rivers and lakes.
• Water Hardness: A water hardness range of 10 to 20 dGH is suitable for Silver Perch, providing a stable environment for their growth.

Feeding: Silver Perch are omnivorous and enjoy a diverse diet. They can be fed:

• Pellets: High-quality sinking pellets formulated for freshwater fish, which will provide the necessary nutrients.
• Live or Frozen Foods: Supplement their diet with live or frozen foods such as brine shrimp, bloodworms, and daphnia to encourage growth and vitality.
• Vegetable Matter: Incorporate plant-based foods, like blanched spinach or spirulina flakes, to ensure a well-rounded diet.

Tank Mates: Silver Perch are generally peaceful but can exhibit territorial behavior as they grow. They are best kept with other robust freshwater fish, such as larger tetras, cichlids, or barbs. Avoid keeping them with smaller or overly timid species, as they may be seen as food. Providing ample swimming space and hiding spots can help minimize aggression.

Substrates and Tank Decorations: A substrate of fine gravel or sand is ideal for Silver Perch, as it mimics their natural environment. Include driftwood and rocks to create hiding places and territorial boundaries. These elements not only enhance the aesthetic appeal of the aquarium but also provide a more comfortable living space for the fish.

Suitable Plants: While Silver Perch may not interact much with plants, including hardy aquatic plants like Amazon Swords, Java Fern, and Hornwort can help create a natural environment. Plants can also provide cover and help maintain water quality by absorbing excess nutrients.

Sexing: Distinguishing between male and female Silver Perch can be challenging, as they exhibit similar coloration. However, males tend to be slightly larger and may show more pronounced fin extensions during breeding periods.

Breeding: Breeding Silver Perch in captivity can be challenging, but it is possible with the right conditions. They are open-water spawners, releasing eggs into the water column. To encourage breeding, provide a spacious tank with stable water conditions and plenty of cover. Successful breeding often requires a larger group of fish to increase the chances of pairing.

Maximum Size and Longevity: Silver Perch can grow to about 12 to 18 inches (30 to 45 cm) in length. With proper care, they can live for 8 to 10 years in captivity.

General Information: The Silver Perch is a robust and adaptable fish, making it an excellent choice for both beginners and experienced aquarists. Its peaceful nature and striking appearance make it a valued addition to community aquariums.

A Fun Fact: The Silver Perch is not only popular in home aquariums but is also a significant species in aquaculture due to its fast growth rate and delicious taste, making it a sought-after fish for both farming and recreational fishing.
