Key Features:

• Appearance: Isidori's Elephantnose Fish has a streamlined body with a long, tubular snout. The body coloration is typically brown or gray, and they may have subtle patterns.
• Snout and Electric Organ: The elongated snout houses electroreceptors, specialized cells that detect weak electric fields in the water. These electroreceptors are used for navigation, communication, and locating prey.
• Size: Adult Isidori's Elephantnose Fish can reach a size of around 4 to 6 inches (10 to 15 cm) in captivity.

Water Conditions:

• Temperature: Maintain a tropical environment with temperatures between 75°F to 82°F (24°C to 28°C).
• pH Levels: Aim for slightly acidic to neutral water conditions, ideally between 6.0 to 7.5.
• Water Hardness: Keep water hardness in the soft to medium range, around 5 to 15 dGH.

Tank Setup:

• Provide a tank with a secure lid as these fish are known to be skilled jumpers.
• Include hiding spots, caves, and driftwood to create a comfortable and secure environment.

• Maintain excellent water quality through regular water changes and proper filtration.
• Monitor water parameters and adjust as needed to mimic their natural habitat.

Behavior and Sensory Perception:

• Isidori's Elephantnose Fish are nocturnal and have poor eyesight.
• They rely heavily on their electroreception abilities to navigate, communicate, and locate food.

Caution and Expertise:

• Keeping Isidori's Elephantnose Fish requires a certain level of expertise due to their specialized needs.
• Approach their care with caution and provide a suitable environment that replicates their natural habitat
