I there bud it looks like you got some live rock with mushroom corals on or they could be sponges.

Hi, @Nemokat. Welcome to ReefBase.

Yeah it looks like a mushroom from the picture. It should be green, blue, purple, etc but it's had little to no light and/or high nutrients (nitrates and phosphates) so it's lost it's colour.

If you have good lighting and maintain good water conditions, it's colour will return.  :glad:

No it won't hurt bristle worms help keep the place tidy in my opinion :)

If a coral is brown, it's either insufficient lighting or high nutrients, with the exception of some, like some leathers which are naturally a tan colour.

Insufficient lighting negates the need for colour pigments to shield the zooxanthallae algae from too much light, and high nutrients cause the zoox to bloom.

That one will be green. What is your lighting and nitrate and phosphate readings? If those are up to scratch, that 'shroom will colour up.
