The Ornate Bichir (Polypterus ornatipinnis), also known as the Senegal Bichir, is a remarkable and prehistoric-looking species of fish that's native to the freshwater rivers and swamps of West Africa. With its distinctive appearance and unique behavior, the Ornate Bichir is a popular choice among aquarium enthusiasts who are fascinated by ancient fish species. Let's explore the key features, care requirements, and considerations for keeping Ornate Bichirs in your aquarium:

Appearance:

• Primitive Look: Ornate Bichirs have a unique, elongated body covered in bony plates, giving them a prehistoric appearance reminiscent of ancient fish species.
• Coloration: They have a dark base color with striking patterns of lighter spots and markings that vary among individuals.
• Size: Ornate Bichirs can grow to sizes of around 16 to 18 inches (40 to 45 cm) in captivity.

Behavior:

• Nocturnal Behavior: Ornate Bichirs are primarily active during the night and tend to be more reserved during the day, often hiding among decorations or in the substrate.

Tank Setup:

• Tank Size: Provide a tank of at least 75 gallons (283 liters) for a single Ornate Bichir. Larger tanks are recommended for multiple individuals.
• Substrate and Decor: Use sand as the substrate to protect their delicate underbelly. Include hiding spots like caves, tubes, and rocks for them to explore and rest.
• Filtration: Efficient filtration is necessary to maintain water quality and provide gentle water movement.

Feeding Habit:

Water Parameters:

• Temperature: Maintain the water temperature between 75°F and 82°F (24°C to 28°C).
• pH Level: Aim for a slightly acidic to neutral pH level between 6.0 and 7.5.
• Water Hardness: Provide moderate water hardness with a hardness level between 5 and 15 dGH.

Care:

• Tankmates: Keep them with larger, non-aggressive fish that won't harass or compete with them for food.
• Nocturnal Nature: Provide hiding spots and dim lighting to accommodate their nocturnal behavior.
