[Pufferpunk]

Sponge.

[matt612]

Have u got a better pic looks like individual mushrooms can see mouth in centre and frilled edge on one

[matt612]

And also one is in process of splitting

[Pufferpunk]

Hmmm... then they're terribly bleached. I think I do see a mouth on one of them.

[matt612]

I had the same ones good sign them splitting i i must have good eyes can see mouths and frills on the left one if i zoom

[matt612]

White furry mushrooms

[Pufferpunk]

Not white, bleached. Was this rock in the dark?

[matt612]

Have u never seen these mushrooms before see them all the time at my local reef shop when i started my tank i filled it with mushrooms of all colours shapes these are normal almost transparent not in any way bleached

I had simular on my lR the lfs guy tolled they were sponges. Same description as you they look like little.mushrooms grouped together and there seems to be an opening for a mouth.

My lr was kept under a light in store all be it not very powerful one. One of these "sponges" is vivid yellow but the rest are all milky white and spreadin like mad

[matt612]

The yellow one is probably a sponge the rest sound like mushroom anemone

[vorton]

The.milky ones have a thin transluscent skin on them. Very odd but very cool

[matt612]

Great starter coral really easy don't need special lighting and spread like mad
