Mr. Feather lost its crown

So I couldn't resist to not buy anything and walk out of the store, I picked a feather duster which I thought was pretty cool. The guy just lifted him out of the water and dumped it into the bag wit water. (Not even gentle enough) So I came home, acclimated him even-though his crown was attached with a tiny tiny string to its body then. I tried to reach down easy on him, lift him and put him in the water. But he let go of his crown. ((((((((((( I was so disappointed. Here's a picture of the worm reaching out of the tube. I guess for food. ( they say it will eventually grow back in 3 weeks. But I'm not sure if he can easily get food and survive till then. Any ideas? BTW I'm calling the store to see if I can get store credit for it even-though they have absolutely no guarantee on their livestock.

If you can't take him back, I would try spot feeding him until his crown grows back.

 

I'll try that. Is there anyway it would actually take his crown back if I put it next to him?
