Not This is my idea for my mixed reef, 125 gallon tank:
Livestock:
LPS, SPS, and other softies
BTA
1 Blue Girdled Angelfish
1 Coral Beauty
1 Red Coris Wrasse
1 Green Coris Wrasse
1 Yellow Coris Wrasse
1 Diadem Dottyback
1 Yellow Tang
1 Regal Tang
3 Blue/Green Chromis
I have chosen this livestock because of the ease of taking care of them and their colors. Especially the Blue Girdled Angel
Filtration:
Live Rock and Sand is my natural filtration
BRS GFO and Carbon mixed Reactor
Bubble Magus Curve 7 Skimmer
Not sure about sump, probably DIY of a 40 breeder
Maybe Bubble Magus Doser
Lights:
Mix of T5s and LEDs
