Peacock/Lesser/Eyespot Spiny Eel

Description

The Peacock Eel (Macrognathus siamensis) is a small, elegant spiny eel species native to the slow-moving rivers, lakes, and swamps of Southeast Asia, particularly Thailand, Cambodia, and Vietnam. Its slender body features a golden-brown coloration with a series of striking, eye-like spots along its back and tail, resembling a peacock?s plumage, which gives the species its name.

This eel thrives in environments with sandy or muddy substrates, where it can burrow and feel secure. It is a nocturnal predator, emerging at night to feed on small invertebrates such as worms, insect larvae, and crustaceans. In the wild, it prefers habitats with dense vegetation and low water flow.

In aquariums, the Peacock Eel requires a soft substrate, plenty of hiding places like driftwood and plants, and subdued lighting to replicate its natural conditions. It is a peaceful species, making it suitable for community tanks with similarly sized, non-aggressive fish. However, it may consume very small tankmates if hungry. With its distinctive markings and gentle demeanor, the Peacock Eel is a popular choice for aquarists seeking an exotic addition to their tank.
