I run a 40 gallon tank with just easy/budget soft corals (mostly).
I do have a duncan and one small favia-looking thing which are LPS but mostly just soft corals.
*my tank is a lot more basic/simple than yours though
Not on purpose, but I my decades old tank is being overrun by discosoma to the point that I have no recourse and regret putting the first one on 25 years ago.
