Clean up crew for aggressive tank?

[spider2928]

What would be a good clean-up crew for a 55 gallon tank with a barred moray eel and a volatin lionfish? Or is that not even an option with those fish in there?

id say your only options are some 6+ inches conches, but the best cleanup crew you could get is probably you. yeah with those you cant keep to many inverts that are smaller than 5inches
