The problem you will run into with Wild caught Catfish is you more than likely will not get them to accept pelleted food but it would be worth a try. If after a few days they are not eating, eat them

Fertilized eggs would do best if you can hatch them and get the up to eating flake food. Don't forget, they will need lots of space as they are cannibalistic when young and will eat their siblings.

Keep us posted on what you decide and don't forget, photos...lots of photos.
