It is simply not true that captive bred clownfish are reluctant to host in anemones. Don't believe everything you read. Reasons to buy captive bred include:
1. not removing another fish from its ocean home.
2. Captive bred are relatively disease free. Unless they caught a parasite at the store you buy from, they are disease free. No Brook, no Ich, no nothing. In other words, they are very hardy and they, well, live.
3. Captive bred are accustomed to captive living. This makes for a happier fish. They have known nothing but aquarium life.
