Used Live Rock, Some Tag alongs

I picked up some used LR the other day, and it exploded with life quickly after, just wonding what i have on there, so i can find out how i sohuld be treating it

Some kind of mushroom?


This is small, but theres a few sprouting up around the rocks.


One rocks now covered in these:


and finally:



Any help would be great, thanks

 

The first one is a mushroom (good). The third is GSP(good). The fourth is a Majano Anemone(not great). Most reefers kill these with kalk paste.

 

Yes, the fourth is definitely not good at all. It is a majeno anemone. Kalk paste will do the trick on it.

 

ummmm 3rd picture is xenia. 2nd pic not sure. 1st is mushrooms.... And last but not least is an anemone of some type. 4th is the no good mejano

 

Yeah, the 3rd pic looked more like xenia to me as well.
But there are some really ugly star polyps out there, these are not star polyps though, notice the feathers om the tentacles??

 

In pic #2, both pink ones and the skinny white one are different species of foraminiferens.

 

Thanks all, I'll try the kalk on the anemone, hopefully i can stop it now before too much spread. Its a shame, because the actually look decent, and react very well with food.

The mushroom looks that red color, and when i took the first picture, i forgot the flash was still on, and even with 300W of light in my 55 gal tank, the spots didn't show untill the flash hit it. looked good, so i used that one.


Looks like your right with number 2, looks like Homotrema rubrum, a spieces of foraminiferens.

Récif France Database (It's French, but shows a pic that looks like this one. I guess i should expect some canadian jokes to come )

The 3rd looks likea xenia. sorry for the bad pic, i should have turned off the pumps to get a better shot. They move around a lot with the flow.


Thanks all for the help, i was given some SPS with the rock, and i'll be posting soon with questions on them as well
