Ribbon eel eating tank mates?

[yraveh]

I have a black ribbon eel that dine on a large silverside daily.
In recent week I noticed the disappearance of my scissortail, blue damsel ( I have had them for years) and a rock blenny.

Is it possible that the eel consumed them?

It is hard to say but ribbon eels hunt by smell and their eye sight is not especially good so it is unlikely that it hunted and captured the fish. By the way, you might consider giving it raw squid as it is a favorite of most eels. Feed with a feeding stick or tongs and remove if not eaten.

Do you know if it likes anchovies?
