Pineapple sponges, a harmless filter feeder and beneficial to your tank.

They look like pineapple sponges to me as well...

The PS has a thicker rounded body like a pineapple with much shorter tentacles such as in the OP's pix.

Aiptasia have more of a whimsical body with longer flowing tentacles...

Also mcgyvr that is a GREAT link, I had never seen that one before, Kudos!!!

Pineapple sponges and aiptasia look nothing alike and its super easy to tell one from the other..

Those are very clearly pineapple sponges..

Agreed. Pineapple sponges look like a white pineapple. Aiptasia have a relatively thin column and long tentacles.

Definitely don't look the same... Take a look at the link below (courtesy of mcgyvr) and you can see what both look like.

well i spent like 3 hours yesterday getting sponges out of my tank (wish i didn't)

In my reef tank there is a direct correlation between how fast these grow in my sump and plumbing and water changes.If i am busy and skip a water change or put off for a few days and over feed .

but as everyone else said they are good not harmful at all but would be ugly to have in the display itself

Won't really be a problem either way. It is very likely that you didn't get every last one so they will likely repopulate if the water chemistry allows.
