Critter ID in my Sump

[CoralsAddiction]

Could you ID these things for me? Are they pods or snails? I have a bunch of baby snails on the glass of my tank but these things are bigger and look more like pods.

Look like pineapple sponges ( harmless filter feeder ).. Do they move?

Thanks, I have posted this question in the Reef discussion section and got the same ID.

How do I post my own topic to this site?
