I have a Tesselata Eel that is 18 inches long and for the first 3 weeks nothing worked on feeding him. I went to a Chinese Store and found Marque Quality Pak Brand Wild caught squid. 3 lb box. These are whole squid about 5 inches long. My eel went from having food in his mouth and spitting out to an eel that attacks the squid. This saved my eel. He was looking terrible. I tried krill, shrimp, live feeders, etc. This worked. Hope this will help somebody else that has an eel that will not feed.
