This is under whites and i guess it does look a little greener than normal and i think thats because ive been dosing trace elements lately and that includes iron which is known to cause yellow coral to become a little greenish but i assure you its usually yellow but then again alot of people also have diffrent opinions on what looks yellow and that looks green, if you search Google for a green montipora i dont think this is what you will see haha but yea
