I know you guys get this all the time, but I went to melev's site and couldn't find them and the search engine is too busy. Can I get some help on identifing these?

I just bought a rock of zoos and they look fine. I have them in QT and doing some FW dips to be sure. These things were letting go in the FW.

They are hard and white and vary in size and number of legs/spikes. The spikes were kind of anchored into the zoo polyps. This was the best I could do on pics -they are tiny.

Thanks for any help you can offer.
 
from my experience with them... they are predators. they are hard like starfish and use the pointy parts to poke the zoanthids.. if your colony is loose, you gotta check under the base of polyps cuz they are there also. that particular pest comes on zoanthids collected from the solomon islands. oh yah, don't bother trying to FW dip them away. it won't help.. you gotta manually pick em off.
 
They aren't using the pointy parts to poke the zoas. The zoas are growing over them. There is physically no way for these things to prey on zoanthids. They're nothing more than amoebas with calcium shells. They can come in with zoanthids from any part of the ocean.
 
i have to disagree greenbean. from my experience in getting zoas. i've seen those things come on zoas that come from the solomon islands. the indo zoanthids have a larger round version of that pest. oh and yes, i spotted one on a zoanthid polyp. it had the "pointy" part into the polyp. i pulled that one off a zoanthid polyp and there was damaged tissue there. can you please explain that?
 
The zoanthid grew over the test of the foram. When you pull the foram out, you leave a hole behind just like if the zoa grew around a rock and you pulled the rock out.
 
great. you should know they are a nuisance to zoas. i've plucked quite a few of them off the indo zoanthids. you would know since your in the field they do quite a bit of damage to the when they pierce the flesh of the polyp. this is just my observation after inspecting 700-800 zoanthid colonies.
 
This genus of foraminiferans is photosynthetic. They are not predatory. There are absolutely no macro-predatory or parasitic foraminiferans. I'm not even sure how you think this organism could attack a zoanthid.

Sorry could not let this by. :lol: :lol: :lol: I see them in lobster traps every day with 12 legs most are around the size of the bottom of a can. DUNNO if there the same, but they will kill lobsters and crabs in a trap in know time.. if there the same critter. Diffrent color a litte. Not sure
