PJ Cardinals not eating

[revrick3]

90gl. tank 4 months old, all water parameters right on line and consistent. Have 1 yellow tang, 1 foxface and few soft coral and zoa. Added 3 small PJ cardinals one week ago and have not gotten them to eat that I can see yet. I have a very good population of copepods in tank, could they be eating these. They have also picked a secluded corner of tank out of site and never venture out. Is this normal for this fish, how can I persuade them out and to eat? Thanks guys you have been great in my new venture.
Forgot to add, I have tried many different types of food and dropped it almost on top of them, pellets, algae sheets, shrimp, brine shrimp soaked in garlic,

They don't eat when they have eggs in their mouths?

I am not expert, but I am sure if they hungry enough, they will eat. I would assume they are not always going to eat when you want them too, LOL it's like they have a mind of their own, hehe

This is yet another reason why fish should be in quarantine first. They are not used to your food and not used to your schedule. They are scared. They SHOULD start coming around, or at least pick, soon.
