So I have a HOB overflow cup (actually two) in my 150G system, and there are a couple of "sponges" in those that basically act as mechanical filtration. Of course they get clogged with time and I know the proper way to clean them is to squeeze them out in post-WC water to release all of the debris.
My question is this: I have little filter-feeding critters (I think they're amphipods) that live on those sponges and are very happy there, and I would kind of like to keep them there between cleanings. At the very least, I have a mandarin goby in my display that would just love a snack. Is there any way I can clean these sponges while somehow saving the critters, or are they doomed whenever I need to clean them?
