Nemo and white carpert anemone?

[Aquattro]

not all clowns host in all anemones, and the species of clown that do host in a particular anemone don't always host in the one you have. Sometimes they wait before going into it, and sometimes they never go into it. Also, white is generally a sign of bleaching in anemones. Make sure your water is perfect, you have MH bulbs and you feed the thing regularly.
