Half Banded Spiny Eel (Macrognathus circumcinctus)


A small-growing and intricately patterned freshwater eel, the Half Banded or Zig Zag Spiny Eel is found in a variety of habitats throughout Myanmar, Thailand, and other parts of Southeast Asia. Hardy and more outgoing than many of their relatives, these fish make a unique addition to medium to large aquariums and will generally do well with any fish too large to become a meal. Like most spiny eels, they can be a bit slow to feed at first, so care should be taken to ensure they are getting enough food. Frozen bloodworms are usually accepted readily.
