Ok a few new things to ID =)

[Florida8]

These are something alive, they looked like blobs of raised coraline and now they have red somethings coming out...

These?

These just showed up in large numbers a few days ago... still here - lots of them.



*****

These look to be coming out of a very old LR dead coral clear little things with a pudgy center, alive and catches food on the little tips


*****
Green plant? Looks like a dandelion tip that you blow and make a wish on? LOL... the tip - flowery part is not out all the time, only when feeding.

I have quite a few of these as well.



And these?



sorry for the blurs, the pods crawling on the glass were messing with the focus.

Ok, photos 1&2 is red caulerpa. A macro algae that has the potential to become a problem so keep it pruned well.
Photos 3,4 & 5 are all different types of hydroids. These can become a nuisance as well but can be control through water changes and lowering available nutrients in the tank
Pic 6 if you are referring to the red thing looks like a foraminiferan. Harmless detrivore.
The last pic, are these things mobile? The banding on them makes me thing peanut worm.
