Peacock Eel Care Guide
Macrognathus siamensis · Freshwater Fish

What Peacock Eel look like
Macrognathus siamensis is an elongated spiny eel with a pointed snout, small dorsal spines, and distinctive ocelli or eye-spots near the rear of the body. It is a fish, not a true eel.
Behavior & temperament
Peacock Eels need soft sand so they can burrow without skin damage, a tight lid because they escape, and peaceful tank mates too large to eat. They are often shy at first and may need targeted feeding after lights out.
Diet & feeding
Peacock Eels are carnivorous micropredators. Feed frozen or live bloodworms, blackworms, tubifex, brine shrimp, mysis, chopped earthworms, and small sinking carnivore foods once trained.
Behind the name
Macrognathus means large jaw; siamensis refers to Siam, now Thailand.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
