Hey, welcome to the site.
You can buy some bloodworms and they'll go crazy for those, once they've settled in.
Just give them some time to get over the stress from netting and being rehomed.
Go sit in front of your tank , spend time with the fish and talk to your fish.
This may seem stupid, but i do this every time i get new fish, and they will recognize you very quickly.
I got all my big fish to eat out of my hand within days, or mostly some weeks.
if you want some pointers on handfeeding, i'm more then glad to help.
