Clown fish don't host pink tips naturally, and you may have a hard time getting a clown to host at all.
As for tank bred clowns, they will host just the same as wild caught. Try posting some pictures of clowns hosting anemones on the sides of your tank ( facing into the tank, not at you!!). This has worked for my tank bred ocellaris. They started hosting my Bubble tips after about 4-6 weeks. There is a thread somewhere regarding this.
This seems to work for many people, but may not work for everyone. It helps to have the right clown and anemone. Get Joyce Wilerson's book on Clownfish. That lists most or all of the combinations of clowns and anemones. I don't have it here with me right now so I can't help.
