I purchased my Gymnothorax polyuranodon about 3 months ago and until this day, i havnt seen it eat! I bought some guppies and ghost shrimp, and after being in the tank for 3 months, they are all still there! I tried frozen blood worms, frozen brine shrimp, pieces of real shrimp, dried shrimp and nothing! I have never seen him eat! Hes alive so i guess he must be eating something! My question is, How can i get him to eat these foods? I have heard that creating a different water level helps, but what does that mean and how do i do it? please help me on this one! Anyone!!! Thanks!
