New Fish Question

[my names bond, james bond]

i currently have an 80 gallon tanks with a turboflotor 100 hang-on, a lifeguard fbf 300, and a filstar canister filter for up to 175 gallons. My fish are a 3 inch Niger trigger and a 5 inch Lionfish. I have had both these fish for 2 years but now that i have some extra money i want to get a clown trigger and a french angel(3inches each) to finish off the tanks. what order should i place them in and how should i do it to get the least aggression possible?
thanks
Jon

French angels get pretty big. Are you planning to upgrade? If so, i'd get the clown trigger (but a little smaller), then add the french last.

I believe you have to be careful what triggers you mix.
