I think you'll probably end up getting rid of either the FH or the Red Devil...... but not before they eat/kill your clowns! I'd be more concerned about loosing them [clowns] before you choose a fish to "86". Those little clowns are defenseless agains the power and the aggression of the FH or RD! So..... it's only a matter of time and of which one decides to begin the kill.
