ORA Picassos not interested in food, for the second day

[slojmn]

Hi all,
I picked up my little baby ORA Picassos on Saturday, they came into the LFS on Friday. He fed but not sure if they ate. They looked very healthy and spunky in the tank at the LFS. Seemed to acclimate greaat Saturday afternoon. Tried multiple types of food (Formula2 flake, Formula one frozen, small sinking pellets, mysis cut up very tiny, freeze dried cyclopeeze, Arctic Pods) with no luck on Sunday. Tried flake and Frozen Formula 1 thus far today, no luck.
They are both hanging out near the top in the back, one looks to be a little less active than the other. Both are staying in same area with no interaction from tank mates. Tank mates never paid them any attention since they were introduced. What do you think??? Should I be worrying?? My helfrichi pair ate the next day when I added them to this tank. Usually fish will eat within 24 hours for me. This has me worried. They seem to have no interest at all.
