Three ID's

[tur4k]

First I have this clear tentacle thingy...

Second, I have these green...polyps? anemones? Right at the base of the Christmas tree rock.

Third, I believe this is sponge, but would like some confirmation. The stuff under the Yellow Polyps.

that first picture looks like a homeless hermit crab. I had one crawl out of it's shell and it looked like that

not sure on the second picture, but the rest are sponges

You were right about the hermit crab.

The second looks like an Anemonia Majano pest.

#1 Sponge, harmless filter feeder.
#2 More information. If you approach it with something, a net or chopstick etc. does it retract fully? When if it retracts does it have a hard skeleton that shows?
#3,4,5 sponge.

#1 Hermit Crab without a shell OR a molt from a hermit crab
#2 Majano Anemone
The rest are harmless sponges.
