View Full Version : Mystery hitchiker polyps on Fiji Pukani Live Rock

Got some "Fiji Pukani" live rock from livestockusa.org about a year ago.

Over the past year all kinds of neat critters--fanworms, snails, spaghetti, etc. have appeared. There were some zoas, but they died as the rock cured.

Anyhow one patch of little brown tentacled things started growing in one of the sheltered locations--not too much light gets there but it's visible.
Kept an eye on them because I though they might be those bad anenomes "aiptasia".
But as they've gotten a little bigger, it doesn't look like anemones.
I think I see a stony skeleton inside, and short conical tentacles around a mouth.

Can anybody suggest what this might be? Will it cause problems?

Hidden Cup corals I believe. (Phyllangia americana)

Thanks for the ID!
Looked up the name & seems like lots of folks find these on their live rock.
