Ribbon eels are extremely finicky eaters. They are pencil thin and have very small mouths. This prevents them from being able to eat things other eels could typically eat. Additionally, they don’t have the same razor sharp teeth typically seen in eels, meaning they can’t tear their food into manageable bites as easily. The ribbon eels, from my limited experience, do best when served live ghost shrimp or other small, slow moving animals. Frozen silversides are usually small enough for them to eat as well, but the eels tend to get a little shy when a hand is placed into the tank or the dead food is being presented. Lastly, like with all eels, the ribbon eels are escape artists. They can and will find a way out, so do the best you can when putting a lit over their tank.
