If you have any rubble in your DT then just grab a few pieces for the invert QT along with a little dry rock and that’ll seed the rest.
I’d avoid “aquascaping” as any large pieces or hiding places make it a pain to keep track of the inverts. Scattered small chunks 1-2” will form a nice substrate for bacteria and algae while maintaining functionality.
