advice on nano reef tanks

Hey guys!

As I stated in my intro I'm not exactly 'new'... but I am. I just upscaled tanks and was wondering if anyone had suggestions for a nano reef set up. I get that everyone likes/preferences are different and that many change light specs. but my corals have been doing great under the lighting that's standard in the 14g biocube. Was wondering if anyone has suggestions on what corals to add I've currently got:

Fish-

1 true & 1 false percale

tiger goby



Inverts-

1 blue foot hermit

snails



Corals-

a bubble coral, in the sand

a pink goniopora, in the sand

a frog spawn in the back corner, in the sand

2 buttons (red & green)



I get that most of mine are aggressive, but i also understand some corals can tolerate 'specific' aggressive corals while others cannot. ANY help would be great!
