After just a week, my mandarin has already decimated my tank's pod colony! My pod culture (thanks to Mark B!) isn't fast enough to keep up with my mandarin so I ordered two bags of live pods from AlgaeBarn. My sump has plenty of rubble rock and chaeto for pods to live in. My tank OTOH may not have enough rocks for the pods to hide/live in. Since marinepures are known for being super porous, I was wondering if they would be suitable habitats for pods? Or are the holes only big enough for bacterias?
