Julii Cory not eating; advice needed

[ClarkyTheSharky48]

I have 4 Julii Corydoras that I got from the same store. I went there to get some shrimp and browse other fish (mainly looking for swordtails) but while waiting to recieve help was looking at their julii corys. However there was one that was not like the others. Like, 2 in, very plump, I actually confused him for a leopard corydoras (which was like three tanks down). When I asked about him, the person working there said that he had just finished his quarantine and was surrendered because the house he came from couldn't provide proper care. She said they hadn't gotten the adopiton sign up yet, but said "we ask for proof of habitat or enclosure, and also want to know if you have any plans to purchase more julii corys today or if you have any already, and also how many." After showing a pic of my tank (36 gal, planted, pebble substrate) she asked a few more questions about food and stuff and I signed their papers and adopted him. I checked my parameters before putting him in and it has been a few days, and I haven't seen him eat. There are 7 cherry shrimp, 4 nerites, and the 5 Julii corys including adopted fish. I followed the feed schedule I have, flakes and pellets, fast, frozen brine shrimp day yesterday. 4 of my shrimp have disappeared, not like they hide then come out after a while, I mean they went off the grid; vanished. The big guy isn't eating at all, he looks for food, will act like he is digging, but even when he sees it and goes over it, he ignores it. I quarantined him too just to be safe, would feed him in AM and food was gone when I checked on him before bed. If he is nervous, I get that. But the food will get eaten up by all the other fish within a few hours, so I can't tell if he is eating at night. If he's eating the shrimp, which I don't think he can, I'd be ok with that rn tbh. They are pretty small, have molted a few times, and some are super small, so I am not worried about that, because it's honestly just an issue of him getting food, especially since he was surrendered.

It may be that he doesn't recognize these as food just yet, who knows what his previous owners fed him. Give him some time to figure it out, he will eventually learn what's food with what you offer. If he's not losing weight, I wouldn't worry too much. If he's getting skinnier, then be worried.

It's not a good regular food, but offer him an algae wafer, he may have been fed those lots of folks do as their only food or worse use them as "cleaners" and not feed them at all.
