Hi all,
I thought you might find this interesting, I spotted this with a Mesoscope in a lfs and returned the next day to take some photos. Do you think that these hydroids would stop an Acro from opening fully as the polyps in the immediate vicinity are closed?

melev said:Barry, are you talking about the Digitate Hydroid? I've never seen a problem with them, but Dr Ron seems to believe they can cause trouble.

One of the few I have left is totally infested with these, and I really think they were there when I bought it. It is expensive, you think they'd take it back based on that?
I wonder if there is a symbiotic relationship between the Acro & Hydroids/Hydrozoan Polyps as they appeared to living within the coral/polyp. Could the coral be using the hydroids as a defence mechanism?melev said:I'm pretty sure we are talking about the same creature Barry. Dr Ron has some information about Digitate hydroids on his site. I didn't see the first tinier one, but the other one is pretty much an exact match. They can get quite a bit longer, typically at night when the lights are out.
