Poriferan sponge. Exposure to air will slow them down or stop growth

Thanks for the reply. There is an Emporer and a regal angel in the tank; maybe they’ll recognize them as a snack.

Possibly benthic foraminifera as well, which are also filter-feeders. Brief air exposure does not seem to impact these protists. These are also rock-solid, while the sponges in my systems have all been “squishy.”
