Possibly a variety of cryptic sponge. The forked tips are the clue. Here's a type that grows on glass and starts off as worm shaped. You can see the youngest individuals here fit your description.

Yeah, I could not find any photos anywhere of something that has formed tips like that! Thank youPossibly a variety of cryptic sponge. The forked tips are the clue. Here's a type that grows on glass and starts off as worm shaped. You can see the youngest individuals here fit your description.

Agreed, the forked tips are unlike any hydroids I've seen. The other possibility is benthic formaniferans. There's a seemingly endless variety in nearly every shape and color immaginable. Many branch in a similar manner. They're often misidentified as sponges, hydroids, etc. Harmless filter feeders.
