Resolved Red hitchhiker - It's growing! (It's Nemastoma)

So on a rock in my tank there's this small red hitchhiker. It's not hard, but not soft either. I haven't touched it by hand but I'd guess it's texture is like that of a gummy bear. I don't have a clue what it is. It's pretty small, you can see it next to some paly polyps. What is it?



It's dead center on the rock just above the small polyp.

 

Look like red mushrooms to me?.. Or it may just appear round... If its not a shroom or radial I would then lean towards either a type of sea squirt or sponge...

 

Looks like a sponge or possibly a tunicate.

 

It's definately not a mushroom. It is about as tall as it is around and kinda has an odd shape to it. I wish I could take a better picture.

 

Red bubble algae. Your best bet is to take the rock out of the tank, CAREFULLY remove the bubble from the base of the stem. and rinse with tank temp salt water. This stuff gets out of control if not taken care of immediately.

This is the same thing next to a monster Aiptasia that got boiled.

 

Rinse well if you pop one of the bubbles. It WILL spread throughout your system. Nothing I'm aware of eats it. Not even my emerald crab wanted anything to do with it.

 

Sorry guys, it's definately NOT red bubble algae either.

 

Here's the newest photo. As you can see it's getting larger. It has layers I suppose like a head of lettuce that can be separated. It's not hard like rock. I hope this new picture helps a little.

 

Has it spread?
Has it eaten anything else?
Do you like it? (I kinda do)
Would you leave it alone and observe more? ( I would)

Sorry, form the picture- good one btw- I don't think I know what that is

;-)

 

Looks like it could be Nemastoma, which I think is very cool.
