In honour of Holland's excellent start to Euro 08, here's something orange.
This is an orange cup coral (tubastrea sp. I believe). in the day time you often see kind of reddish/orange blobs on the reef. at night they open up like this to reveal dozens of hungry polyps. Tubastrea is a truly predatory coral; in aquaria it is often direct fed with small shrimp. They tend to close when lit up with torches so photos are hard to expose but I'm reasonably happy with this clump.
