So I broke down the 90 gallon yesterday. This morning was sump time. I pumped out most of the water - (RIP Pods, thank you for your service.) After I dragged it outside to hose it out and do a deep clean, I got a surprise. This worm-ish thing came floating out. Ick Eww. I have no idea exactly what it is or how long it's been there. It's gone now. All I can say is wow. It was not a bristle worm, so who knows? It is on a standard envelope for size perspective.... ignore the doodle. LOL
