sponges?

[parrotchute]

Found these while trying to repair my skimmer (see post in reef talk, probably SHOULD be in lighting & equip), but no idea what kind of creatures they are...any idea?

They're pineapple sponges. Good for you tank and are filter feeders, so they help clean the water. They will grow to a high number as the tank matures and then decrease in number later, Mine stay pretty much out of the way in the sump and filtering areas. Some even live in the return line, and in my cheato.

cool, thanks bobby! I accidentally squished some with my fingers trying to see if they were odd shaped salt deposits. Poor bastards.

They are also called scypha or q-tip sponges. They are normal hitch hikers and are harmless filter feeders.

they're cool...I saw one of them that looked a bit like aiptasia and it scared me (it wasn't)
