i am not sure what these brown polyps looking thing are, they just suddenly grew on my dead coral rock or live rock i bought at the fish place

I have no information about these fish, i think they are killifish but im not sure what they do or if they harm other fish or harm my tank? My uncle caught them in the ocean bay so any info about them would be great

I believe this is a sponge i wish i could have taken a better picture but it was between the crack of the rock

Without a clear picture, it is almost impossible to identify your hitchhikers. I would be willing to guess the first pic is button polyps. If you can find the macro setting on your camera, it would definatly take a better pic for you.
