We often talk about the nasty hitchhikers we get, like my montipora-eating nudibranchs, but one of my favorite aspects of this hobby is the nice surprises we sometimes get. My favorite by far is this lobophyllia (at least I think that's what it is). It came as a larva or tiny polyp on a clam I bought. It also came with a feather duster worm that was too small to see at the time. The clam only lived one year, but the feather duster lived 3 years, and after almost 11 years, the lobo keeps getting better.
