So bought this frag plate about 2 years ago completely covered in different mushrooms well I had a big crash in the tank and lost literally the entire plate bought some ricordias and missed my mushroom plate so I started a new one the frag plate has never left the tank the tank is healthy now and all of a sudden this pops up it looks like some kind of sps but have nothing that looks remotely like it in any of my tanks so I assume it was under the original mushrooms or something and started growing but I've never noticed it before it just randomly showed up (it is super neon green by the way) will take better pics when I can find my lens
