How big is the SFE ?? if he is larger you could try a brittle star or maybe a couple of sand sifters. All an urchin would do is graze on the coraline algae and other algaes in the the tank. If you have a small SFE (10" or less) I wouldn't even add a brittle star, the star may be able to get a hold on the eel.
