Seaweed? Keep or not?

[Dolphin1]

Can you tell me what these 2 different types of seaweed are and whether I leave them alone or remove them? Also, I am assuming that is corralineon my rock?

If you don't like it remove it. Many marine plants can become invasive as their roots will be hard to remove from a rock.

Thanks - I do like it as it adds a bit of colour but didn't know if it was a good or bad thing to keep? There are too different types and I didn't know if either of them were good for the tank.

The biggest issue is that they can grow faster than many corals in your tank. So that becomes an issue in the long run. I am not a fun of them due to how hard they are to keep under control in an aquarium. Fish don't eat them so you end up manually removing them and they never go away as they will grow back from the tiniest roots in the rock
