This little guy will eat any and everytime I feed, but since he's not gonna grow to be a monster its kinda more what he needs then growth rate power feeding.
I've been feeding my 6" peacock eel an earthworm every night, just regular not nightcrawler. Seems to be a good rate for him, doesn't remain lumpy after 24 hrs like my bichirs do.
one of mine is a very very active feeder. eats once a day and will fight of the 6" pictus for the food.
i had another that wouldnt eat anything i gave him. he ate only baby snails in the tank(used to have a problem with them). hmmm could be why he crawled into the filter, that was the only place were there was still baby snails
