Happy New Year to All! I introduced my first corals last week and now find a number of mystery guests on my glass and possibly in the water column. Can anyone tell me what these are?

I have this Duncan coral that has been forming bulges. And overnight they have cracked open/caved in. I don’t know if this is how Duncans grow new heads or it’s some sort of burrowing pest. the brown tissue within the cracks doesn’t give much confidence

Does anyone know what this fleshy-looking spiral thing is, at the base of the duncan? Sorry for the blues/poor quality. I can try to get a better picture tomorrow, if it helps. I had thought it was a new head growing - it's been there since I bought the frag two and a half months ago. It's...

Hello, I have a couple of those things on the glass? Any idea what they are? Good or Bad?

I love weird things in my tank. But I do like to know what they are and what they eat before I let them run loose in my tank. Arrived in a package of pods.

Good afternoon all, I am on the downhill side of a ********’ fight with bryopsis (fluco ftw), and noticed some tubes on some frags now that they are not covered in algae. I am reading a lot of conflicting info, so hoping someone could give me a definite ID, so I can treat accordingly if needed...

Hello I noticed these hard white stringy things on the Skelton of my torch as well as these red bumps on the torch. I was wondering if these are some type of pests or if it’s normal for that to be there.. thank you for any feedback.
