Pineapple sponge = good

Pineapple sponge. Sometimes called qtip sponges.
Great things I let them live in the sump but pick them out of DT if they get in there only because they're not pretty.

Agree with all of the above, beneficial little pineapple sponges!

Looks like pineapple sponge to me. Harmless filter feeder and a sign of good water quality. Will come and go as tank ages.
