Biocube 32 about 5 months old. No fish, just cleaner shrimp, some snails and corals. This literally just showed up on top of sandbed. Best description is a rehydrated white raisin.

Sponges are beneficial filter-feeders.

Try not to take it out of the water while returning it to your display - air does them no good.
