i too have a couple of lovely fires. one will only feed on regular worms but the other started eating mussel and shrimp a couple of weeks ago. before that, he wouldnt eat anything but worms. I starved him from friday to tuesday and by then he was so hungry he would eat anything. no problems since. the other eel, even after that starvation period, would not touch anything else. some eels just don't go for other things. a friend of mine has exactly the same with a fire. i wouldnt try for dry feeds, that will almost certainly be a no-go. i must add that since i feed one mussel and shrimp, it does seem to grow faster.
