Well if we're definitely speaking of the spotted mandarin (too lazy to review thread) They may be more inclined towards eating foods you add to the tank.
I have a picky anthias that I hatch live baby brine for on a daily basis. don't know if they started right away as it wasn't really for the mandarins - but when add the BBS the mandarins are out & clearly eating them. They seem to kind of pretend to be picking them off the rocks. they go after them with gusto!
Anyway it couldn't hurt to hatch a teaspoon of these & feed them to your tank a couple of times & see what happens.
Caveat: I feed enough of these at once to "fill" the tank with them - it's an amount equivalent to maybe 2 cubes of frozen food.
I wish I could tell you if they took to them immediately or not _ I just wasn't paying attn.
Keep feding those pods daily with DT's!!
Buy a piece of uncured live rock & put it in your tank (assuming you're fine with the bioload) it should cause a copepod explosion on that rock
Buy any fast growing macro algae - especially chaeto
I know you have lots of pods... do you know what kind? My tank is p-a-c-k-e-d with amphipods, but it I don't think these are what my mandarins seem to go after
HTH

Glad he turned up - maybe he was kinda having an adjustment issue or was sick & will feed like crazy now.
Now that you've found him, do you see him continuously? Sounded like it from "again this morning".
