i just recently (like 2 days ago) purchased a fire eel, hes already about 8 inches, however, since ive had him he will not eat, i tried bloodworms, he didnt touch them, i had been told that they are more active at night so i fed at night and turned lights off, still wouldnt eat, then i tried live ghost shrimp , i added about 20 and found most of them dead that following evening, is it just because hes getting used to the new tank or am i doing somting wrong, his tank mates are doing the same thing, and they are a B ghost knife and 2 cory cats
