Bad, you should remove them.

Glue over them, take a lighter to them, cover with kalk paste.

Going to be a long process removing all the rock to avoid them from taking over.

Ugh is it necessary to even remove them or can i just keep them what do they even do anyway

Those look like aptasia to me. The brown guys sprouting from the top of the rock? They look like feather dusters, but are a stinging anemone. Several methods to get rid of them, but getting rid of them you should defiantly do.

Hydroids are in the jellyfish family and can look similar. But aptasia is more common to aquaria. Without a better photo it's hard to determine which it is.

Need a better picture. But far more common than hydroids.
