Not that I don’t believe how it has gone with fire eels for some of you, but my experience with them has been quite the opposite. At first, they can be hard to get feeding, and mine still don’t eat pellets. I’ve had two of them for over a year now, and they are pushing around 20” (they were 4” when I got them). They are voracious eaters. I feed them night crawlers, frozen shrimp, frozen tilapia, frozen krill, and a few other things. I have also fed them frozen bloodworms and live red wigglers in the past. They eat all of it and stuff themselves with as much as I will feed. I’ve been pretty lucky with them considering the issues I’ve heard about people having.
