   The Black Ribbon Eel seen above is a juvenile. The Blue Ribbon Eel is bright blue with a yellow mouth and is the adult color of a mature male black ribbon eel. A female Ribbon Eel is yellow.

   These eels are only recommended for experienced aquarists!

   These are probably the hardest eel to keep since they can be finicky eaters, often refusing food.The Ribbon Eel, Black Ribbon Eel, Blue Ribbon Eel should only be kept by very experience marine enthusiats as they are extremely difficult to acclimate to captivity. We have had success with only one! Getting it started on ghost shrimp and then guppies.

Great video of a male Ribbon Eel in the wild.

The beautiful undulating movements of the Ribbon Eel captures the eyes and hearts of most saltwater enthusiasts! There have been several more success stories in keeping these creatures alive in captivity as of late, but they are still suited to advanced aquarists who are willing to take the time to train them to take frozen/thawed foods. This video is one of a male in the wild. Juveniles are black and females are yellow to greenish blue or green, although females are not seen as often. They can reach almost 4 feet, but due to their skinny and compressed bodies, they do not demand a tank as large as deep bodied eels would need!

Great how to video to get your Ribbon Eel to start eating!

This video shows how to elicit a feeding response when you have one Ribbon Eel. The rosy red fish was alive and when it wiggled out of the grabber. Notice that the aquarist pretended the grabber was another eel chasing the fish, then the Ribbon Eel got excited and grabbed his meal! Notice that the lights are dimmed down, and the tank is transitioning to lights off, so the brights are low. This is the best time to train them to eventually eat frozen/thawed silversides.

I bought a Black Ribbon Eel 4 weeks ago and he has eaten 4 dozen ghost shrimp, frozen mysis, live brine shrimp, frozen brine shrimp, frozen krill and dried fish flakes. He eats everything. Will he turn blue?

    Yes, they start off as black males, but once they mature they become blue females.

I've had my ribbon eel for about a week. I've tried feeding it everything from frozen to live it seems like he just doesn't want to eat. I have PVC piping to make him comfortable. What should I do?

  • Anonymous - 2017-03-13
    Try feeding him colorful live fish like goldfish or guppies. Use a grabber arm to make it look like another eel is trying to compete with him. Good luck!

    They can be tough to get feeding. The techniques we've used is with a poker made out of rigid 1/4' clear tubing with a paper clip attached with a rubberband to the end. Then we pierce live food (like the ghost shrimp) on the paper clip end, and offer it in front of the eel's face. The paper clip is blunt so it doesn't hurt them, and if the food is moving they pay attention and will sometimes strike.  If nothing happens, then we kinda bump them on the nose. But being bumped on the will sometimes elicit a bite reaction. This way they get the food, and then they start understanding that it is food. Still, there are some that simply won't feed. Good luck!
