Lime Green Sponge?

[Maverick986]

I was cleaning my tank yesterday when I noticed some sort of greenish-yellow thing in my coral. When I was taking pictures this morning I also noticed a redish tube looking thing, and purple thing with what looked like little nubs on it as well. I have never seen these things before, as it is just a few days ago in the tube in the picture there was a feather duster, but I didn't see the feathers from it last night or this morning.

Redish thing:

 

Purple nubby thing:

 

All three:

 

Anyone have any idea what these are? I tried looking them up, but haven't been able to find anything! Also, this is on my Candy Cane coral.

LFS has the exact same green sponge in a AP24. I'll ask them if they know the name of it.

Awesome, thanks. My main worry was if it was something i need to remove, or if its fine w/ my coral being attached to the same thing.

pineapple sponge. i ended up removing mine as sponges can be finicky and chemically nuke your tank if unhappy

I always thought that pinapple sponges are little clear looking things? not neon green-yellow?

Could it be: a) Clathrina canariensis (Yellow Calcareous Sponge) or Mycale laevis (Orange King Sponge)?

 

I found pics at the link below, and these 2 look similiar, maybe?

Yeah, that's definitely not a pineapple sponge. I have pineapple sponges here and there as well as that same neon green sponge growing under a rock in my tank.

 

I dont know what the name of it is.

I've got the same one under one of my rocks. Well, could be on top now...my tank is all tore up. Seems to like low flow low light.

They are totally safe, I have had literally pounds of all of those in my tank for many years. Consider them free filtration. They wont harm a thing.
