Hi All,
Wasn't sure if this should go in the hitchhiker ID or here - but these are all recent discoveries in my tank...
1. I think I have gotten rid of the zoanthid nudibranchs I had, but now I'm seeing something else on my zoanthids (not nudi eggs either). Any idea what these white growths / spots are? I should note, the zoas are opening - they're only closed b/c these pictures were taken at night. 3 pics:
Are they destructive to the coral?
2. I also have these white spots all over my glass (I moved a nerite snail in the photo to closer to the spots so you can have an idea of size - match-stick head size). Any idea what they are? I thought coralline (and maybe that's it?), but they're growing in areas other coralline isn't (further down the glass in most cases):
I don't think it's the same as what's on the zoanthids, but I could be wrong... These are very round while what's on the zoas is irregular shaped.
3. There's only one of these in my tank, but it's been slowly growing. It looks like maybe some kind of fungus that's grown outward? It's on the underside of a dead coral branch (that I just used as live rock) so it doesn't get a ton of light and I wouldn't imagine it's an algae:
Any ideas what that is? Harmful? Thanks,
--Kyle
