Any idea what these are?

First off I'll say I have a guess but I won't say what I think it is yet. I'd like to see if anyone else has seen this before. It's not coraline algae and I can remove them whole with a little brushing or my fingernail.

Small purple/whitish spots. Perfectly round. Attached mostly to rock surfaces. I don't see any on the glass or eggcrate.

Nope not a clue! Tuning in>>>>

Just a guess, a species of flatworm.

They don't move. All are perfectly round.

Do you think it's algae or animal?

 

[Shep]

Could they be a polyp type coral that reproduced sexualy and thus is all over the tank?

Animal.

That's what I'm thinking.

Possibly a type of Foraminiferan.

That's a new word to me. I'll have to look that up.

Possibly a type of Foraminiferan.

This would be my guess as well.

I have pocillapora in the tank and I was afraid it was larvae. :neutral: Glad to see it's something harmless.
