![]() Pineapple sponges. Pretty much all tanks will get them, especially in overflows, sumps, and filters. They are beneficial filter feeders.

![]() I'll vote for tunicates as well. I belive that the pineapple sponges have only 1 primary hole and they look more prickly, while the tunicates always have 2 primary holes and look glassy. My completely non-educated opinion only.

![]() They look like tunicates to me. They have an incurrent and outcurrent syphon.
They are filter feeders and should not cause any problems in a tank. I've actually purchased larger species.

![]() Based on the info from you guys and the photo of the pineapple sponges, I would say they are tunicates. They definitely have both incurrent and outcurrent syphons.
Thanks for the help with the ID! Glad I don't have to get rid of them because they are neat looking... |
