Purple dots/bumps ID. Currently cycling my tank.

Hi. I am noticing these little bumps around the tank. My tank has been cycling for about 2 weeks now. I got live rock from another hobbyist locally, no idea what they had in the tank previously. The live rock was in a couple of buckets exposed to air for a while.

Anyhow, I am trying to ID what these little bumps are. Hopefully they are good algae. Sorry for awful camera phone pics. I have not edited the colors at all.


Bumbs scattered on a rock





Larger bump with tall purple one in the back.

IMO it looks a bit like coralline aglae (good stuff)

Hard to tell from the pictures, but could they possible be vermetid snails? The description of one of the bumps being tall is what makes me think that. I have what I believe are vermetids in my tank and they are generally small purple/pink spirals with smokestacks (for lack of a better word) that have thin strands like spiderwebs coming from them.

Yes, I know they don't move. Forams come in all shapes and sizes. Yours may never grow much larger than they are, or, they may grow into small branching forams. It's nothing to worry about and no need to monitor them. They are very common too.

Edit - here's an example of some branching foraminiferans:

OK sounds great. Really appreciate your help. They definitely look like what you have in that picture, just smaller obviously.
