In one of the pics I have a big ball of zoas. I'm going to frag them today, and try to get them to spread better. I'll post pics when I'm done to let you guys know how it goes.
When my clown pair lays their eggs, they are as bright orange as they are, and turn dark by the next day. Could your pair have laid eggs already? I've also got orange algae on an old coral skelton; been there for years.
