Looking for some help trying to fiugre out what these are?

[j67345]

Hey all...I had a tough time getting good pictures, and these were the best I was able to snag. Any chance anyone knows what some of my stuff is?

These guys have a brown trunk, but the middle is a light blue...


These ones look kind of similar, but one kind is orangish & the other one is a greenish color...


And this stuff just started randomly growing in a few different spots on my rock...figure it's some sort of algae? Kinda cool looking, but I've never seen anything like that before?


If anyone knows what they are & can help, I'd really appreciate it!!

3rd one kinda looks like plating coralline. Kool if it is.

I have that plating stuff in a number of different spots. It just appeared on day & has been growing a bunch of plate thingies! I thought it was some sort of cool algae, but I've never seen it before!

1st one is common blue palys.Watch out they can be aggressive and take over pretty quickly.

If someone else verifies it as plating coralline, it is in fact an algae and a good one at that.

I'll keep an eye on those palys...no wonder the frag was so cheap!

Anything I should do to keep that plating coralline (if that's what it is) happy?

3rd looks like purple cap. Grew like a weed in my tank
