Not the bladder snail itself, but whatever is attached to it. I have no idea if they're parasites or not or if I should be concerned but the snails seem, honestly, fine? I've noticed most of my bladder snails have them.

(Not marked captive because whatever these are, I did not intend for them to be here)

Double-crested Cormorant (Phalacrocorax auritus) an aquatic diving bird in the Cormorants and Shags (Phalacrocoracidae) family. Conservation Status: Vulnerable (S3) in California.
Neck appears kinked in flight. Large, rounded throat pouch is yellow-orange year-round. Eyes often appear blue. Breeding adults have a wispy, white crest, a tuft of feathers curving back from behind the eyes. This dark, long-bodied diving bird floats low in the water with its neck and bill raised. It is often seen standing upright near water with wings spread out to dry. It is larger and has a shorter tail than the Neotropic Cormorant.
The Double-crested cormorant is the most widely distributed cormorant in North America, and the only one likely to be seen inland, even in the desert near bodies of water. At the coast, Double-crested Cormorants tend to nest in trees, unlike Brandt's Cormorants which nest in mud impressions on offshore rocks, and Pelagic Cormorants which nest in sides of cliffs.
