live rock or coral

hello , a month ago I purchased a piece of live rock? from the the LFS in the live rock bin, it looked like a piece of coral ( thats why I bought it) there was nothing on it, now all of a sudden it is turning burgundy color and looks a little furry, can this possibly be a piece of coral? i did notice a few weeks ago it has a few feather dusters on it , any ideas
Thanks

The rock in the ocean is dead coral, and that's what you have. The color you are seeing is algae and probably some cyano if you are just starting to cycle your tank. Maybe some coraline algae, hard to say from the descriptors but it isn't living coral.

live rock

Hi , the tank is 3 months old and this piece is the only one that has that color, just thought it was odd and looks like a brain?
Thank You

Ah I see in your profile. That is a skeleton of a brain coral with algae or cyano building up on it

If its a hard algae it's coraline and good. If its slimy its Cyanobacteria and sign of most likely too much nutrients and needs to be remedied.
