Couple of things in my RSM130 that I don't know what they are (being a newbie)

1: A transparent/whiteish trumpet thing that appears & disappears from the rock at different times of the day. Its at the back of the tanks so I can't get any other look/photo of it currently.


2: Some light green stuff on one of the rocks but its covered in a clear skin which has a couple of holes in it


Neither appears to be doing any harm but Id be interested to know what they are.
Thanks

Not sure what the first one is. More pics of that one would be helpful.

The second pic isn't that great, a bit blurry. But based on your description it sounds like it may be either a colonial tunicate or a sponge.

will try and get some better photos. theres quite a lot of little blue sponges on other parts of the rock and just behind this green thing there is a small yellow sponge.
