Advice: what would you get?

[nofish4u!!]

My tank has been up for 6 months now (it's a 120g FOWLR).
I currently have:
1 Koran Juv. Angel
4 Firefish Gobies
2 Perc. Clowns
1 Yellow Watchman
1 Pistol Tiger Shrimp
1 Cleaner Shrimp
20ish Hermit Crabs
2 Turbos
1 Sally Lightfoot
2 Emeralds
1 Boxing Crab
What are some suggestions you would have for future fish? I'm thinking about getting a couple more clowns and 2 brittle stars. Other than that, I'm not really sure. Open to all suggestions! Thanks in advance!

Be Careful Adding More Percs!! The Two You Have May Have Already Teamed Up And They May Gang Up On Any More. The Best Way To Keep Them Is In A Pair Or In Odd Numbers After 2 Of Them. With Multiples You Will Have Them Split Up And Pick At The Other Less Dominant Clowns. If I Was You I Would Think About More Turbos First, They Will Rock A 20 With All The Room But You Need More To Keep Up. Other Than That I Would Be Careful How Many More Fish You Add, With The Amount You Have Going You Don't Want To Overpopulate!!! Depending On How Much Live Rock You Have Going And For How Long It Has Been In There You Could Think About Maybe A Type Of Blenny Or A Mandarin Would Be Sharp!!!
Good Luck
