Salt water aggressive tank 100 gallons?

ok im going to be starting my first salt water tank soon. I am a beginner and i want to have an aggressive tank. i plan to cycle to the tank with damsels then get a lion fish to clean them up. after that i plan on getting a porcupine puffer,some tangs and a fox face lo. What else can i get that is relatively easy to take care of and wont break the bank or crowd my tank. thank you :)
