Hi all. I have a mated pair of Gold Stripe Marroon Clownfish. The male bounces from host to host a bit, but the female is sticking close to my torch coral. Lately (last week), she has been pushing the torch around a bit, and hollowing out the cave behind it. She kicks up sand with her tail by moving it back and forth really fast, and I have seen her picking up bits of shell/rock and carrying it out of the cave. Is this a sign of distress? or is she preparing to spawn. Hopefully the latter. Please let me know if this is normal, or something I need to be concerned about. Thanks, Bobby
