Couple weird things popping up in my tank, need some ID help please

[JTM4UG]

in addition I have been getting alot of mini carpets. The green ones are really neon and almost looks like it could be eggs or something with small darker green strands. The polyp looking ones are right by my main powerhead in my tank on a rock.

Hydroids?

That's what I was thinking but they look a bit bigger than the ones I've seen in my tanks.

I used to get them from brine shrimp eggs when I kept dwarf seahorses.

They definitely look like hydroids, not massive pests but not benevolent.
