I removed these from my tank. Does anyone know what they are? I saw something that they might be Medusa hydroids. They are in my dwarf seahorse tank so I’m trying to see if they can hurt the seahorses
Are these Medusa hydroids? And are they harmful?

I can’t speak to if they are harmful or not for seahorses but those are Medusa Hydroids I have some in my tank right now!
Definitely hydroid medusae: I don't know if their sting would hurt dwarf seahorses or not, but hydroids would compete with the seahorses for food, so they're probably not something you want in the tank regardless of sting.
