Hi y’all, new-ish tank owner. Has anyone encountered this opaque branch-like thing in their shrimp tank or tank? My shrimp tank is only 4-5 months old. This is the second time I’ve seen it and it kind of resembles a hydra, but it looks different?? It’s only appearing in the crevice’s of the foam rocks (the tanks background) and it’s growing close to the surface of the tank, towards the light. I feel like it’s an obvious answer but I’m V interested in knowing what this is!
