Peacock Spiny Eel (Macrognathus siamensis)

Description:
The Peacock Spiny Eel is a captivating freshwater species known for its elongated, eel-like body and eye-catching patterns. Its body is light brown with a series of small, circular "peacock eye" spots along its sides, giving it its name. This shy, nocturnal species thrives in aquariums with soft substrates and plenty of hiding spots.

Size:
Up to 12 inches (30 cm)

Aquarium Size:
A minimum of 40 gallons is recommended for a single adult Peacock Spiny Eel due to their size and burrowing behavior.

Water Parameters:

• Temperature: 75°F to 82°F (24°C to 28°C)

• pH: 6.5 to 7.5

• Hardness: Soft to moderate

Temperament:
Peacock Spiny Eels are peaceful but shy. They can be territorial with other bottom dwellers if space is limited. Despite their size, they are generally non-aggressive toward larger tankmates.

Group Size:
Best kept singly or in a well-spaced tank if multiple eels are desired. If housed together, ensure there are ample hiding spots to reduce territorial disputes.

Compatibility:
Peacock Spiny Eels are suitable for community tanks with medium-sized, peaceful species such as larger tetras, rainbowfish, gouramis, and peaceful cichlids. Avoid housing with very small fish or invertebrates, as they may be seen as prey.

Diet:
Carnivorous. They thrive on a diet of live or frozen foods, such as bloodworms, brine shrimp, blackworms, and earthworms. Some individuals can be trained to accept carnivore pellets, though they often prefer live foods.

Care Level:
Intermediate. Peacock Spiny Eels require soft, sandy substrates for burrowing, stable water conditions, and a diet rich in protein. They are sensitive to poor water quality, so regular maintenance is essential.

Planted Aquarium:
They can be kept in planted aquariums but may uproot delicate plants while burrowing. Hardy plants such as Anubias, Java Fern, and those attached to hardscape materials work best.

Invertebrate Compatibility:
Not recommended with small invertebrates like shrimp or small snails, as they will likely be seen as prey.

Additional Notes:
Peacock Spiny Eels are known for their burrowing behavior and are skilled escape artists. Ensure the aquarium has a secure lid to prevent them from escaping. They prefer low lighting and appreciate caves or driftwood for hiding during the day.
