Colin's Angelfish Not Eating

[Steve and his Animals]

I recently acquired (about 2 weeks ago) a Colin's Dwarf angel. Looks perfectly healthy, good weight, no visible issues, not incredibly shy either. However, like the title says, from what I can tell it doesn't seem interested in any food I've offered. I've tried mysis, arctipods, R.O.E., live baby brine, PE calanus, and nori has been in the tank occasionally for my princess parrot. I do see him poking around the surfaces in the tank looking for food, but nothing floating.

Any tips with this specific species, or picky dwarf angels in general?

Time to try some Masstick?

Do fish typically go for that without mixing other stuff into it? Or is it a food that you hope they nibble on by accident and like it?

I’ve never used it, but I see that it comes cookie dough like; You stick it to glass, you stick it to rocks, and they supposedly find it rather irresistible and they nibble. Seems to have great reviews for finicky fish— I suggest you buy just a small size and give it a whirl.
