I've been told this was a Red Planet coral (1st pic) and some montaporia (2nd pic)... I recently acquired some flatworms on my mushrooms and a couple other corals...I bought some RX Flatworm solution and have done about 3-4 treatments with a water change after each treatment 24 hours later...I believe thats about the time I started noticing some color change (maybe 3rd treatment)...I just did another water change this morning but no treatment but I'm really concerned for the Red Planet...!!! Can anyone help me out with what's going on...I'm a new tank owner but the tank is 8-9 yrs old and well established...
