The Dwarf Yellow Eel, Gymnothorax melatremus, this is a relatively small eel that is quite rare in the marine fish industry. It is one of the few eel species that is suitable for the reef aquarium as it is too small to threaten medium-sized fish and inverts. The Dwarf Yellow Eel will feed primarily on a diet of enriched mysis shrimp, chopped meaty foods, clam, and squid.
