Need advice on what else I should add to my tank

[cryptics]

Hello all,
I haven't posted in a bit but I have been reading (have to do something at work). Ok my tank is a 90g with a 30g sump mixed reef. Mainly LPS and Zoas/Pally right now but with Mr. BTLDReef's help I am starting to get into SPS. The tank is a year old. I had a nasty flatworm infestation but am starting to get it under control with the current inhabitants. Here is my current stock list
Pair of Perc clowns
Black Blenny
Ornamental Leopard Wrasse
Pair of Melanaris wrasses
Mandarin
Chevron Tang
First before everyone says so i promise to add pictures tonight or tomorrow The tank is very calm everyone gets along. The last addition was a little over a week ago so I am not going to add for a few weeks but wanted to get your opinions on what to add. I was thinking of getting a female Leopard wrasse but not sure if i am pushing it with three wrasses already. My original plan was to add a Flame angel but I am leary now since the tank is so calm worried he may start crap. One thing is the leopard wrasse I have is totally calm like it should be but I got him from a friend who he was a model tank mate for until a Hippo tang started picking on him. He killed the Hippo Tank hence why he is in my tank now Maybe a butterfly? I am just scared by how fragile they are. Ohh and i consider Cardinals the equivalent of furniture. They freak me out how they seem to look at you and never move so no cardinals!
Thanks for the advice!

Welcome back! Stop being such a stranger here, or I will stalk you on the other site

I'm depressed right now as I just lost my Copperband Butterfly that I've had for quite some time today.
I'd look into a small harem of Anthias, they'd add some nice color to the tank and are usually peaceful to all their tank mates. Tropical Island has some BEAUTIFUL ones right now, can't remember the name at the moment. Under the LEDs, they glow.
I don't see any issue with a Flame Angel. Make it your last addition and get a healthy specimen and you should be fine.
What about a bottom dweller? Like a little goby or something?

Your tank to me is already full, as soon as your clowns spawn your calm tank will be over. I have a pair and they clam a third of the tank as there's. No butterfly, your clowns will harass when they spawn, mine will attack the lattice butterfly if even comes close, plus they require pristine conditions.
