New Dwarf Lionfish Help

No sign of the lion. Lost all hope at this point. I’ll make sure to get a larger one next time to eliminate my eel possibly snacking on him.
Eel still gets along with my copperband, both banggai’s, and filefish. And most recently a blue reef chromis that i picked up. Maybe since the lion was slower than the other fish the eel mistook it as food.
