Kidding. As with many other deep sea creatures, Persus has learned how to hunt from the eels as well as others. When’s one prey is too fast to chase down, he lies in wait, hiding in an alcove or nook if available. When they come across him, he will strike them unaware and bam. Food.
He respects Eels just like any other sea creature. He fails to understand how they can leave such patient lives.
Also there’s one nuisance of a troll associated with eels that he finds himself constantly butting horns with.
