Like most fish, it's likely still trying to adjust to it's surround and is timid. New fish usually are because they're not use to a person walking in/out or food just dropping from the water column. Keeping trying to feed small aquantities. Sometimes it take a day or so after arrival before they get around to start trying. Eventually you can start trying other food from frozen, to pellets to flakes. Eventually they will understand anything dropping from the water column at a certain time is food and it should be eating :beaming-face-with-smiling-eyes:.
