What kind of pod is this?

Was wondering what these were, to find out if they are herbivores. They have small claws and I see them fighting each other every so often.
I think they are helping me get rid of hair algea and diatoms.

Munnid isopods. They’re good for your tank. No worries. They’re herbivores.
