Every animal type will react differently to sudden shear forces. I once tore a Botryllus colonial sea squirt just by moving it through the water. Now that was delicate. True cryptic.
Sponges do consume oxygen and I run a bubbler in the semi-cryptic and cryptic zones. So they will need access to oxygen in a power outage. You can help that access by designing large open water surface areas.
