Spiny Eels (Macrognathus siamensis), also refferred to as the Peacock Eel, are native to Thailand, Cambodia, Laos, and Vietnam. They’re commonly found in the slow-moving backwaters of the Mekong and Chao Praya basins. Spiny eels thrive in bodies of water that are sandy, warm, and heavily vegetated. These fish are prolific in the wild but uncommon in the pet trade.
The Spiny Eel is a nocturnal species and spends most of its time burrowed in soft sand or silt. Despite its carnivorous nature, the fish is peaceful, shy, and keeps to itself.
Ensure the substrate in the fish’s tank is several centimeters deep to accommodate its burrowing behavior. Avoid abrasive, harsh materials like gravel to protect the fish’s delicate body from injury.
Spiny eels often uproot plants and decorations. Tie decorations and plants securely or bury them firmly in the substrate to prevent the fish from dislodging them
